[parser] Cannot parse boolean literals

[kaushikcfd]

Minimal reproducer:

In [1]: import pymbolic as p

In [2]: p.parse("True")
Out[2]: Variable('True')

In [3]: p.parse("False")
Out[3]: Variable('False')

@kaushikcfd any reason this is still open after #58 was merged?

[kaushikcfd]

Yep, it was indeed fixed. Thanks!

For posterity, it can be verified as:

>>> import pymbolic as p
>>> p.__version__
'2022.2'
>>> p.parse("False")
False
>>> p.parse("True")
True
>>> p.parse("True or False")
LogicalOr((True, False))
