returning a list:
func(@foo);
- func( split /:/ );
+ func( $text =~ /\w+/g );
Then you've just supplied an automatic C<scalar> in front of their
argument, which can be more than a bit surprising. The old C<@foo>
which used to hold one thing doesn't get passed in. Instead,
C<func()> now gets passed in a C<1>; that is, the number of elements
-in C<@foo>. And the C<split> gets called in scalar context so it
-starts scribbling on your C<@_> parameter list. Ouch!
+in C<@foo>. And the C<m//g> gets called in scalar context so instead of a
+list of words it returns a boolean result and advances C<pos($text)>. Ouch!
If a sub has both a PROTO and a BLOCK, the prototype is not applied
until after the BLOCK is completely defined. This means that a recursive
