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)}); ?
