Then of course, PyGRASS has no chance to know that and the recent type
enforcement addition will force you to use string instead of a list

cls.runModule('g.remove', flags='f', type='rast3d', pattern=['map_1',
'map_2', 'map_3', 'map_4', 'map_5', 'test_flowaccum'])
...
TypeError: The Parameter <pattern> does not accept multiple inputs

(This test ends with error, PyGRASS is used internally.)

I don't know what to do about it besides stating that it how it is or
relaxing the type checks in PyGRASS. Adding some info to the option like
"behaves as multiple=YES" seem too complicated.
