Ok. This tests on classifications made by a file(1) utility
(not on a name of a file).

I find it useful.

Absence of =>0 would imply =>1.
README_FILES/README.lookups says:
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.

If you are blocking executables, consider also blocking related MIME types:
qr'^application/x-msdownload$'i, # block these MIME types
qr'^application/x-msdos-program$'i,
