[Issue 14682] [REG2.037] Incorrect interpretation of ~ []

[via Digitalmars-d-bugs]

--- Comment #3 from Kenji Hara <k.hara.pg at gmail.com> ---
> For some reason, DMD interprets `~[]` as `~[""]`.

Because:
    auto foo = ["foo"] ~ [];

is equivalent to:
    auto foo = ["foo"] ~ "";

At a concatenation expression, arr ~ elem is preferred than arr ~ arr2 when
elem is implicitly convertible to typeof(arr[i]). In the code, the rhs `[]` is
implicitly convertible to typeof("foo") == string.
