yes, you're right. markus also explained sample in expressions too.

but the compiler does get a missing "end", right? But it does not know for
which begin.. I'd be a happing w "missing end" message though during a
syntax check..

As for determining for wc end,

1. maybe we introduce optional endclass, endif, enddef
2. maybe we do python style force indent
