::rant::
Can someone explain why regexp will work with something like:
Code:

set mylameregexp "blah blah($somevarIwanttoGrep) blah"
regexp $mylameregexp $varIamGrepping match myvar

But WON'T work with:
Code:

regexp {blah blah ($somevarIwanttoGrep) blah} $varIamGrepping match myvar

yes I realize that the $ is supposed to indicate an end of line, but then, why does $mylameregexp work? Nevermind, I think I know the answer Razz


Trying to set certain patterns in vars is itself an exercise in creative kludging...

If you replace the braces ({}) with quotes ("") it will be the same.
