16:17 Bug #102 (Closed): Packages: should exported functions be automatically "Protect"ed?: If Package @$aaa@ exports a function @Foo@, then @Foo@ cannot be exported by another Package @$bbb@.
And that's safe... Anna Maria Bigatti

15:49 Feature #101: rethrow in Try .. UponError .. EndTry: I'm afraid that information is lost at the moment (the error object contains the error message only, more information... Giovanni Lagorio
12:13 Feature #101 (New): rethrow in Try .. UponError .. EndTry: What is the way to deal with errors we don't want to catch?
See this example:... Anna Maria Bigatti

16:13 Bug #100 (New): BringIn should map only the indets in its arg: In C4 the function @BringIn@ maps only the indets which actually appear in the arg to be mapped. In C5, the currentl... John Abbott

Yes, but I believe the run-time inefficiency would be ... John Abbott
15:25 Slug #99 (Closed): Function "insert": obsolescent: As far as I can tell @Insert@ is never called by any function in the standard CoCoA packages.
I would like to make... John Abbott

12:24 Bug #98 (Closed): RealRoots should use IsRational: RealRoots incorrectly complains about non rational coeffs in cases like the following:... John Abbott
11:54 Bug #27: CoCoA-5 Manual: Some (many?) examples in the manual use multiplication by juxtaposition. These all need to be corrected so that cut-... John Abbott

17:14 Feature #97 (New): OpenOFile: In cocoa-4 we had (syntax not pretty)... Anna Maria Bigatti
16:01 Feature #90: Make the new fn CoefficientsWRT available in C5: I think we should keep both interfaces: Co**WRT(f, x) and Co**WRT(f, [1,2,3])
The first is very convenient, but the... Anna Maria Bigatti

16:23 Feature #90: Make the new fn CoefficientsWRT available in C5: The interfaces to @ContentWRT@ and @CoefficientsWRT@ are awful -- they seemed reasonable when I designed them, but th... John Abbott
16:10 Feature #25: Function "Call": A find-grep shows that @Call@ appears in the following files:

16:05 Feature #25: Function "Call": Based on the premise "It is easier to add features later than to remove them", JAA suggests that we do not offer a @C... John Abbott
15:58 Slug #96: sort is too slow: It seems highly likely that copies are being made of the list being sorted. Here is my justification:
I created a... John Abbott
12:26 Slug #96 (New): sort is too slow: Sorting is achieved by $list.QuickSort.
Unfortunately it should be called SlowSort. Complexity seems to be quadra... John Abbott

12:38 Feature #95 (New): Error/warning if fn-proc is neither fn nor proc?: My email records show that we wrote about this on 2010-05-19.
C5 distinguishes fns from procs simply by the nature... John Abbott
12:08 Bug #94 (Closed): Default reason for protected variables: Attempting to set a variable which has been @protect@-ed without an explicit reason produces an unsatisfactory error ... John Abbott

17:14 Feature #93 (Closed): Hilbert series: global output rings for non-standard gradings: Hilbert series for rings with standard gradings are all in a single QQ[t].
All other case create a ring for every ... Anna Maria Bigatti

13:25 Feature #90 (Closed): Make the new fn CoefficientsWRT available in C5: JAA has recently added CoefficientsWRT, ContentWRT, and a few other fns to CoCoALib.
Make these fns available to C5 ... John Abbott

16:56 Slug #31: theValue makes copy: The solution is to implement a move constructor in BigInt (and every "huge" data structure ;-) ) Giovanni Lagorio
