Re: Mnemonic for begin/end chars in regexes

Not exactly a mnemonic, but logical thinking

Perl regexes allow variable interpolation and a final $ is taken as a meta for end-of-line

Hence a $ at the beginning would be very impracticable

Otherwise, what would /$var/ be supposed to match?

Very interesting, thanks. Unfortunately, you can see I totally miss this kind of logic. 🌸	[reply]
