This would make for a good blog post/wiki article.  Does one already exist?

If you have a AST macros like in Julia language, I think you can write something like:

@setExpr(a ∪ (b ∩ c));

The main difference is that the compiler gives you a tree in the macro to work on, instead of a string to parse and munge.

Can't you define

template setExpr(string expr)

{

PeggedStuff...

mixin(PeggedStuff());

}

setExpr!(q{a ∪ (b ∩ c)}); ?
