some codes are failed to be compiled

I am using latest cloned wNim/winim, latest cloned-and-built nim on win7 64 bits I compile the kinds of examples in your code via nim c -r xx.nim or nim c --threads:on -r xx.nim

dsl.nim

Hint: gdiplus [Processing]
dsl.nim(17, 1) template/generic instantiation of `wNim` from here
dsl.nim(19, 5) Error: defer statement not supported at top level

and I think the other error sources share the simliar problem:
