--- Comment #1 from Adam D. Ruppe <destructionator at gmail.com> ---
Just wasted ~ 5 mins due to this.

struct Foo {
        void foo() {
                if(1)
                        assert(0);
                }
        }
}

enhance.d(7): Error: unrecognized declaration


Of course in my real code it reported

terminal.d(1681): Error: unrecognized declaration

turns out on line 943, I wrote `void thing() { if() .... } } `. missing the
opening { on the if


Yes, 700 lines apart in the real thing.


Perhaps you say this belongs in a linter but this could have been detected
perhaps by seeing the close brace isn't on the same indent as its corresponding
open line (not always true but can maybebe worth a warning anyway)
