Yeah, I think function or something else is a worse alternative. 
Better leave body as is than replace it with another word. I can 
name my variables body_ if I need.

I wasn't aware of it. Mea culpa.

What I meant If I read a documentation on dlang.org that some 
identifier is reserved for some purpose I automatically think it 
can't be used as variable name. I don't want to check the list of 
reserved keywords every time I doubt. The same I never named my 
variables linux or Windows because they are used in version 
blocks. I have never tested if I can name my variable linux or 
Windows. Don't know if it makes sense.
