class C { int i; }

static assert(is(__traits(parent, C.i) == C)); // Error (line 3)

template Id(T){ alias Id = T; }
static assert(is(Id!(__traits(parent, C.i)) == C)); // OK
---

dmd output:
---
main.d(3): Error: basic type expected, not __traits
main.d(3): Error: found '__traits' when expecting ')'
main.d(3): Error: found ')' when expecting ';'
---

Workaround:
Use `Id` template.
