Implement ForeachStatement for (static) Arrays

I am currently stuck at the semantic analysis.
because depending on the type of the expression that is itterated foreach does diffrent things
how I check If the itterated type has thoose methods ?
-  `popFront()`/`front()`
-  `opApply`

hmm are you sure ? 
too me it looks like :
`for (size_t index=0; ...) {...}`
