when using )copy in an apl ws (see attached fns.apl) or as an apl script

the ⍝∇ in fns f1 is treated as a ∇ and should give the same results as if it
was not there
No.
*⍝ *starts a comment and *∇* closes the ∇editor. After that:
*∇f1[⎕]∇
∇f1[⎕]∇
∇
[0] f1
[1] 1
[2] ⍝
∇

If you omit *⍝∇* then
(1) it will not go into the body of *f1*, and
(2) the ∇-editor will remain open.
The subsequent *∇f2* is not a valid ∇-editor command (only
a stand-alone ∇ closes a function), therefore the line is
passed on to the tokenizer. Which then complains because
*∇* is not a valid APL token:
so now if you actually delete the f1 ⍝∇ you get the syntax error
SYNTAX ERROR+
Tokenizer: No token for Unicode U+2207 (∇)
Input: ∇f2
which is also the same error when running )copy in libapl with the
apl_exec("∇f1"); line
