They do what they were intended for, perfectly well, at least in my book.
[EDIT: Actually, some people do tend to abuse them, and fair point, they don't always withstand mistreatment too well...]

pre-declared:

integer x=0   
for x=2 to 7 do 
end for 
?x -- valid 

not pre-declared:

for y=2 to 7 do   
end for 
--?y -- invalid 

both (should) work equally, except as shown x can be referenced after the end for but y cannot.
