Strangeness. It doesnt quite behave as I expect it to.

I defined a function as follows:

#VAR test {%if( %1=~ "cat", %1, 0)} {_nodef}

Basically i'm trying to pattern match the letters "cat" from the parameter passed to @test().

@test(cat) = cat (true - expected)
@test(catnip) = catnip (true - expected)
@test(dog) = 0 (false - expected)
@test(no kitty) = no kitty (true!?)

Why the heck is the last example a match? Everything returns true if I pass anything longer than one word as a parameter. Does pattern matching not work in this case or something?

I understand I can use %pos to avoid the aforementioned problem in the example. However, I would like to pattern match using wildcards, so =~ is preferable.

-V.
