This is not enough code to understand the problem.  For instance,  
writefln(pattern) prints a class, but we don't see Pattern's toString  
function.  We don't see the code that creates the object and then calls  
check.  Maybe something happens between calls?

It's impossible to diagnose something like this without a working example,  
so you need to trim it down to something that still compiles and fails,  
and then share that entire code.
