Difficult to say, features may not be bad in isolation, but turn
bad when combined with other features. Features can turn bad when
they can be abused for more terse source code in ways the
language designers did not intend, or when scripting languages
are used for larger programs.
But by-name parameter passing is pretty bad. Having expressions
passed into a function executed multiple times backfires real
fast in imperative languages. Such bugs can be difficult to

Lack of consistency (unnecessary complexity?) in the
meta-programming feature set / type system, but cannot be fixed
as it would become a different language.

Simplify the language.
A type system that makes it possible for the compiler to reason
Implementation: clean separation between front-end and back-end.
