Do tags not support the literals None, False, or True? Why would
numbers and strings be supported, but not these? It is possible to
pass these as variables into the context (even in a context processor)
as {'None': None, 'True': True, 'False': False} and it's possible that
someone may be using variables named like this with completely
different values, but it seems odd to me that they're just not
supported out of the box.
If I try passing a None into a tag, I get a "VariableDoesNotExist"
error ("Failed lookup for key [None] in…")
Furthermore, it seems really simple to support by adding something
like this into the top of template.Variable.__init__ (just above the
try)
literals = {'None': None, 'False': False, 'True': True}
if var in literals:
self.literal = literals[var]
return
but that wouldn't be backwards compatible for someone who may be
passing confusing/bizarro variables into their context, such as
{'None': 0}
