-Forcibly replace subroutine with actual code. Note that for performance
-reasons all quoted subs declared so far will be globally unquoted/parsed in
-a single eval. This means that if you have a syntax error in one of your
-quoted subs you may find out when some other sub is unquoted.
+Forcibly replace subroutine with actual code.
If $sub is not a quoted sub, this is a no-op.

-the values. Note that references work as values.
+L</inlinify>. C<$from> is a string will be used as a hashref in the resulting
+code. The keys of C<%captures> are the names of the variables and the values

Which will obviously return from foo, when all you meant to do was return from
the code context in quote_sub and proceed with running important code b.
+=head2 strictures
+
+Sub::Quote compiles quoted subs in an environment where C<< use strictures >>
+is in effect. L<strictures> enables L<strict> and FATAL L<warnings>.
+
+The following dies I<< Use of uninitialized value in print... >>
+
+ no warnings;
+ quote_sub 'Silly::kitty', q{ print undef };
+
+If you need to disable parts of strictures, do it within the quoted sub:
+
+ quote_sub 'Silly::kitty', q{ no warnings; print undef };
