Re^2: Disabling Variable Expansion in regular expressions. (single quotes as delimiters)

hmm ... either it's buggy or I'm doing something wrong

$ perl
print '$x' =~ m'$x'
__END__

$

EDIT:

darn, the $ becomes an anchor for end-of-line

  DB<8> use re 'debug'; '$a' =~ m'$a'
Compiling REx "$a"
Final program:
   1: SEOL (2)
   2: EXACT <a> (4)
   4: END (0)
anchored "a" at 0 (checking anchored) minlen 1

unfortunate!

Rolf Sadly, my testing shows this is a valid indicator. Perl had no trouble with a pattern that had text past the end of string indicator. Though this is the mechanism I was looking for, it didn't produce the result I expected. Thank you so much for your help. It was exactly what I wanted, just not what I needed.	[reply]

Rolf, But that is precisely the outcome I am looking for. I want to detect the improper use of the $. This hard quoted form seems to be the answer I am looking for.	[reply]
