The current impl is:
* reading from @istream@ ... - 11:06 Design #1547 (Feedback): Require decimal mode for ostream?
- I have changed most/all output fns so that they *assert* that the @ostream@ is in decimal mode.
Contrast with input ... - 10:27 Design #1547 (Resolved): Require decimal mode for ostream?

- *STATUS 2021-02-16:* I confirm that the RGB took about 0.35s on my computer, while PD took 473s.
*OBSERVATION:* it... - 18:03 Design #786 (Resolved): MemPool: review min and max loaf sizes
- After the design change noted in issue #1522#note-10, this issue is probably largely irrelevant now.
The current l... - 17:34 Feature #898: New function: cardinality of finite field?
- I have now changed the default defn of @myLogCardinality@ so that it throws an exception; the finite fields overwrite...
- 17:27 Feature #898: New function: cardinality of finite field?

- 17:19 Feature #1219: Frobby version number
- I believe that maintenance of *Frobby* has now passed to the Macaulay group (Mike Stillman, _etc._)
We should contac... - 13:43 Bug #1575: DynamicBitset missing arg checks
- My usual approach regarding errors and assertions is:
* if the fn is the main public fn for that operation (and docu...
