Hm.  I'm not sure that modules *ought* to be interested in it, but ...

One thing a wrapper function might legitimately be interested in is the
context in which it was called.  By that I mean, the wrapper might want
to do something different if the function is being run by the completion
widget code (the call to doshfunc() in zle_main.c), the compctl -K code
or -Y code (zle_tricky.c), or the signal traps (signals.c).  The signal
handlers can sort of be determined by examination of the name, but that's
not what I'd call the best way to do it (e.g. it's possible to invoke the
trap functions manually without a signal having been received), and that
doesn't work for the other cases.
