I'm merging the orange (std.serialization) unit tests with the
test of Phobos. I hit a problem. I'm getting a warning about
unreadable code but it's clear the code is reachable in some
cases because there's a static-if involved. The unit tests
won't run if there's a warning. How can we solve this?
The problem is that there must be a static if branch that is
shortcicuiting the code, right? Eg:
unittest
{
static if (somecondition) return;
unreachable_code
}
The compiler error (AFAIK) for "unreachable code" is not generic
to the code, but only appears for the specific types that makes
the unreachable_code actually unreachable. I've hit this a couple
of times in algorithm's unittests.
The workaround is usally to use static else and/or assert(0), and
to make sure that regardless of types, there is never any code
inserted that could be un-used.
Do you have a link to the actual problem?
