Error: function std.traits.demangleParameterStorageClass is not

Error: function std.traits.demangleParameterStorageClass is not 
accessible from module aveb
etc


problem is that the sub functions are not accessible. i'd like to 
skip them.

wrap your code in another static if:

static if (is(typeof(__traits(getMember, mod, memb)))) { ... }

`is()` gags errors and simply returns `false` for invalid cases.=
