Since my phobos PR for better static assertions was clearly never
getting merged (https://github.com/dlang/phobos/pull/3677), I
moved the code to dub instead:
http://code.dlang.org/packages/concepts
Basically, as long as you pair up your template constraints (e.g.
isFoo) with a suitably named function that should compile (e.g.
checkFoo, not a lambda), then you can write this:
@models!(Foo, isFoo)
struct Foo {
//...
}
And in the case that isFoo is false, you'll get to know _why_ it
didn't compile instead of an AssertError that leaves you confused.
At least it used to and the unit tests pass so I'm assuming it
still does :P
