Is this a bug or am I doing something wrong?

Check out http://dpaste.dzfl.pl/a5ada78fccf5
If my function named "IWillNotCompile" is run, I get an error 
stating "Component!int' and 'Component!int' are not compatible."
If my function named "IWillCompile" is run, there are no errors. 
They do the same thing, just written slightly differently.

Any suggestions?
