What did you do?
./v -g -o vdbg cmd/v && ./vdbg tmpl_tst.v

module main

fn main() {
	$tmpl("tmpl.txt")
}

tmpl.txt:

Hello @@world!

What did you expect to see?

Nothing, it should just compile, because @@ should escape an @.

What did you see instead?

tmpl.txt:9:40: error: undefined ident: `world` (veb action: main__main)
tmpl.txt:9:40: error: expression does not return a value (veb action: main__main)

Instead, the @@ is ignored.
