Now that constant tuples are supported in the parser, eg (1, True, "str"),
it's a small step to allow anything that is a constant to be used with the
pattern:
from micropython import const
X = const(obj)
This commit makes the required changes to allow the following types of
constants:
from micropython import const
_INT = const(123)
_FLOAT = const(1.2)
_COMPLEX = const(3.4j)
_STR = const("str")
_BYTES = const(b"bytes")
_TUPLE = const((_INT, _STR, _BYTES))
_TUPLE2 = const((None, False, True, ..., (), _TUPLE))
Prior to this, only integers could be used in const(...).
