in reply to A regex that does this, but not that?

$var =~ s[\bt(?!est).*?t\b\s*][]g;

Update: sauoq's right. I omitted a \b. 

perl> $var = "thought testament test tot 1 2 3 tesset";
perl> $var =~ s[\bt(?!est\b).*?t\b\s*][]g; print $var;
test 1 2 3

    But, if $var contained "testament", for example, that would fail.

      Yep!. Needs an extra \b.
