Well you can use identifiers that uses __, but certain names that 
uses __ as a prefix will have implementation defined behavior.

I guess for parameters that are strictly __ etc. they're just 
behaving "normal" because there are no implementation behavior 
for said identifiers and thus defaults to "normal behavior".

I also guess it's mostly an issue with function names, field 
names etc. and not really paramters, but I could be wrong.
