Aside downloading them all and loading them into an IDE, Ctrl+F

there is no __traits(isEnum, ...)
I've tried
foreach(m; __traits(allMembers, ...)
{
static if (__traits(compiles,EnumMembers!(m)))
static if (EnumMembers!(m).length)
static if(is(m== enum))
}
I can detect static functions with __traits(isStaticFunction, ...)

No, that's fine. `history[1..100]` gives you 99
