Is there a way to determine whether a given symbol is an alias? Consider

@ChooseMe FuncPtr funcPtr;
alias anotherName = funcPtr;

Handing this module off to __traits(allMembers), then checking for the
UDA on each member, I can filter out FuncPtr just fine. Unfortunately,
anotherName passes the test, but I don't want it to. Is there anyway I
can distinguish the anotherName alias from funcPtr without tagging it
with a UDA? I can't find any sort of isAlias trait anywhere.
I think a better way may be to check if it is a type or not. An alias
appears as a type with the module being the one it is declared in.
While my memory especially at 4am is rusty here:
enum isVarDecl = __traits(compiles, {mixin(GOT ~ " got;");});
Where GOT is assumed to be the string that you got from __traits(allMembers.
It'll be true that it is a variable declaration. False for anything else
e.g. a type.
