Are static constructors guaranteed to run if the module is
imported? Also are static constructors in templated types
guaranteed to run for every instantiation? Even if the
instantiation is never actually used outside of compile time
code, like in an alias or in a UDA?
Is this intended or is it a bug?

Test a;
a.foo(5); // Fails to compile

struct Test

mixin testMix;
