21:05 Design #1546 (Feedback): Improve 'describe' or 'print' for a function
- This is now working fine (after Anna changed the impl of print in the interpreter). Moving to *feedback*.
-
- Since @print@ and @sprint@ now produce the body of a CoCoA-5 function, it superfluous for @describe@ to do the same.
... -
- *IMPORTANT*
* the @describe@ command describes a _value_ and not a _variable_;
* a fn defn *does not contain any in... -
