well, this evening I had been trying the perl -c switch on some
files for the first time, very good, so some synchronicity there! Since
I seem to spend serious time trying to catch syntax errors (aka spelling
mistakes) that will make for some time saving for me.

I deleted a ';' in a regularly used file, and ran perl with the -c
switch and I see it pops up syntax help, the same as when you run the
file with an error. Could be useful, hey! I'll experiment with your
mapping as given above.

thanks
Anne
