Yes, I suspect this will be a source of difficult to diagnose problems.
Perhaps J has reached the point of needing lint?

Me too. I found one of these things that had been in a
working application for years. It was supposed to log some
information out in case of error, but instead it did nothing.
When eventually I needed to look at the log, I discovered
the bug, but too late to help with the problem I needed
the log for.

Subject: Re: [Jbeta] J601M Bugs in Debug lab
I guess "wd'set text *',TXT" is executed as v (n v v) so result is a
verb in J601. It has been suggested to raise an error if there is a
orphan verb that is not assigned to a name within explicit
definitions.
but Roger Hui ruled it out. I still wish this can be done perhaps
provide an additional switch to turn if off just like
"assert." to catch
bugs that are hard to spotted during development.

I found two problems with the Debug lab in J601M beta.
The first was 3 of 27, which says:
"The ? button on the Debug toolbar displays the Debug Help file."
I couldn't find a "?" button on the Debug toolbar.
The second problem was 16 of 27:
"The display should show goo suspended at line 2, with a
syntax error."
Line 2 of goo was
wd'set text *',TXT
where TXT is not defined, which, as a single sentence, resulted in:
+--+------------------+
|wd|+----------+-+---+|
| ||set text *|,|TXT||
| |+----------+-+---+|
+--+------------------+
In J504, the result of the sentence alone was:
|domain error: wd
| wd'set text *',TXT
in a script, the result was:
|syntax error: goo
| wd'set text *',TXT
Lorin Lund first reported this change 2005/12/22.
