This is a diagnostic bug. The error message is highly misleading. Even this
won't compile:

static assert (TypeTuple!(long, int) == TypeTuple!(long, int));

And it *shouldn't* compile, since they are types, not expressions, so they
can't be compared with ==. The code should be rewritten as:

static assert (is(snoC!(int, TypeList!(long)).toTuple == TypeTuple!(long,
int)));

which compiles. Downgrading from blocker to major.
While investigating this I found bug 3451.
