There's certainly nothing wrong with the syntax (i.e. it's perfectly valid 
ruby code). The only thing wrong with the semantics is that you're assigning 
to a local var which goes out of scope right away.

@template is not a class variable. class variables have two @s. One @ is for 
instance variables.

You can't access lcdchar from outside the class. You can however access the 
value it points to from outside (because that's also the return value) and 
you can even access @template from outside (via instance_variable_get for 
example). And no, that's most certainly not the reason your IDE complains.

Copy to where?
