$regexp = "m?" . <STDIN> . "?";
Also be aware that m?pattern? or ?pattern? is a special case of the match operator:
m?PATTERN?msixpodualgc
?PATTERN?msixpodualgc
This is just like the "m/PATTERN/" search, except that it
matches only once between calls to the reset() operator. ...
See
m?...? in

Update: See also qr// in the above section of perlop for more info on interpolating strings into regexes. And see also perlre, perlretut, and perlrequick.
