s~(\$\w+)(\[.*?\])?(\$)~$1$2~igs;

Should do it on all strings you mention above.

e.g.
$string = 'This is a $blahblah$ test to see if $moreblah[junk]$ will
                do some valid $blah[]$ substitutions on
$variables[$thatlookfunny]$';

$string =~ s~(\$\w+)(\[.*?\])?(\$)~$1$2~igs;

$string now = This is a $blahblah test to see if $moreblah[junk] will
                do some valid $blah[] substitutions on
$variables[$thatlookfunny]
