Re^2: 'use strict' without a semicolon can be interesting

[toma]

Perhaps there are a limited number of strictures that use strict knows about. Perl could compare the EXPR list against the known list of possible strictures, and throw an error or warning if the EXPR is not on the list.

I don't know if this is feasible to implement without deep changes, but it does seem possible.

You are right, I meant perl 5.12.1!

[ikegami]

It already does that.

$ perl -e'use strict "foo"'
Unknown 'strict' tag(s) 'foo' at -e line 1
BEGIN failed--compilation aborted at -e line 1.

You passed an empty list which is perfectly valid (i.e. the same as use strict;).
