Are asserts enough to make method @trusted or is something like throw
exception or return error code necessary?
Asserts are a debugging feature. They're not suitable to ensure safety,
because they're simply skipped in release mode.
`assert(false);` is the exception. It aborts the program even in release
mode. So you can use it to bail out when your expectations fail.
So:
assert(expected); /* Don't do this. */
import std.exception: enforce;
enforce(expected); /* Instead, do this */
if (!expected) throw new Exception("..."); /* or this */
if (!expected) assert(false); /* or this. */
