This is a common issue especially for people who know lambdas
from other languages. :)
Your lambda does not do any work. Rather, your lambda returns
another lambda, which is promptly ignored:
Those are some discrete semantics. I know D pretty well and even
I didn't see the problem initially. Anybody else think it's worth
adding a warning to the compiler for this specific case? If this
is the user's intended behavior, then they can rewrite it like
this to be explicit and disable the warning:
_bars.each!(a => (){ a._plots.fillColor = Color(255, 180, 0); });
// ^^ add empty parenthesis before the curly brace
