I think that your idea is good but as others said the "and" literal
could be confusing. �Maybe we can use another word instead of "and"?
The for definition could be like this:
for_stmt ::= "for" target_list "in" expression_list
[ "until" expression ] ":"
suite ["else" ":" suite]
or some other word that clarifies the work of the expression
leave_cond_1 = False
leave_cond_2 = False
mylist = [1,2,3,4,5]
for item in mylist until leave_cond_1 or leave_cond_2:
print item
