I see. I had assumed (incorrectly) that )ERASE and ⎕EX have the same effect.
IIUC, the names interned by any definition are available to tab completion
until they are )ERASEd, even if they are no longer associated with an APL
object in the workspace. I noticed that tab completion sees even names
Hi,
coming back to an earlier discussion, I have optimized the cloning
of
APL values a little. SVN 757.

Hi David,
⎕EX only deletes the current-referent of a name (= the name
at the
top of the )SI stack) but not its global-referent.
If you use )ERASE instead of ⎕EX then
tab-completion will recognize this.

Hi,
not sure. First of all, both IBM APL2 and GNU APL return the same
result in Alex's example:
5 ∘.∘.+ 9
14
5 (∘.∘).+ 9
14
5 ∘.(∘.+) 9
14
Then the IBM language reference says this (
Hi Xtian,
⎕SYL[8 9;]
min. ⎕PW 30
max. ⎕PW 1
It may increase further in the future, but will not decrease.

So it looks like GNU APL parses ∘.∘.+ as ∘.(∘.+).
IBM APL2 and Dyalog appear to parse it as (∘.∘).+.
