So my questions:
- is there a module-crossing equivalent of "version"?
mw covered this. There's more documentation here:
https://dlang.org/spec/version.html#version
https://dlang.org/dmd-windows.html#switch-version
- if not, is there some way I could test for the existence of the enum
can_i_test_for_this? A SymbolExists!() or ModuleHasSymbol!() or
ModuleHasMember!() ?
__traits(hasMember, features, "i_am_not_a_feature")
This is actually what std.traits.hasMember does, but for some reason it
can't take a module as its first argument.

Could it be because __MODULE__ is string, requiring mixin? The following
prints 'true':
enum i_am_not_a_feature = 42;
pragma(msg, __traits(hasMember, mixin(__MODULE__), "i_am_not_a_feature"));
