See https://forum.nim-lang.org/t/4839

type MySeq*[T] = object

proc foo(a: seq[int]) = echo "foo: seq[int]"
proc foo[T](a: seq[T]) = echo "foo: seq[T]"
proc foo(a: MySeq[int]) = echo "foo: MySeq[int]"
proc foo[T](a: MySeq[T]) = echo "foo: MySeq[T]"

foo(@[1,2,3]) # foo: seq[int]
foo(@["WER"]) # foo: seq[T]
foo(MySeq[int]()) # foo: MySeq[T]
foo(MySeq[string]()) # foo: MySeq[T]

For non-builtin objects the overload precedence is wrong.
