What's up with the all caps TRUE and FALSE ?

[ChameleonScales]

In gimpfu, TRUE is not a boolean but an instance:

Code:

➤> type(TRUE)
<type 'instance'>

I'm wondering why it was made that way and whether it can have unwanted consequences to use python's boolean "True" instead in commands of this kind:

Code:

pdb.gimp_edit_paste(channel, True)
