--- Comment #1 from ag0aep6g at gmail.com ---
Reduced:
----
alias TypeTuple(stuff ...) = stuff;
struct Token {}
enum helper = TypeTuple!(Token(), "foo");
----

Workaround: use alias instead of enum:
----
                alias helper = TypeTuple!(fmt[from .. idx1], Token(j, 'd'),
helper!(idx1+2, j+1));
----
