Note quite. That should be 

$ra=Regexp::Assemble->new; 
$ra->add(quotemeta($_)) for qw(list of words);
$re=$ra->re;

or 

$re=Regexp::List->new->list2re(qw(list of words));

[download]

since you start with a list of words, not a list of patterns.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
