Re: [bug-gawk] Another typeof() issue

[Aharon Robbins]

Hi.

The debugger runs as part of gawk itself, unlike most other debuggers
where the debugger is one process and the debuggee is another.

This is an artifact of the implementation. I traced down what's causing
it, and I might could even fix it, but I think I'll just document it instead.

Thanks,

Arnold
