Syntax. Elements of a list in new_RE() can be pairs: [regexp,result],
or just regexps which imply a true result.

Something like:

new_RE(
  [qr'^\.smime$' => 0], [qr'.\.pdf$' => 0],
  [qr'^\.asc$' => 0], [qr'text/plain' => 0],
  qr'^',
)



README.lookups:

REGULAR EXPRESSION LOOKUPS
[...]
Each element of the list can be a ref to a pair, or directly a regexp
('Regexp' object created by qr operator, or just a (less efficient)
string containing a regular expression). If it is a pair, the first
element is treated as a regexp, and the second provides a return value
in case the regexp matches. If not a pair, the implied result value
of a match is 1.
