Can't you do the same thing with functions similar (same API but
different semantics) to std.algorithm ones that generate
expression templates?
auto person = persons.filter!(e => e.name == "John");

What's wrong with this syntax that doesn't reqiire macros? It's
more uniform with the rest of the language:
Ranged!(int, 10, 20) i;
