Simple question (I think anyway) 1

[travs69]

When using the cgi module

why can't I do this
@out = grep /param(what)/, @test;

I have do to do
$what = param(what);
@out = grep /$what/, @test;


Probably something simple and if the proper way is the second way that's fine to, but I need some explaining so I understand why.

param() is a funtion (or method), it will not work inside a matching (m/pattern/) regular expression. The parenthesis in this context are for capturing patterns in memory, not sending arguments to functions.
