for statement, adding a STEP clause?

Hi,

there is a chance to add a STEP clause to the FOR statement in plpgsql?

something like

FOR i IN 1..100 STEP 2 LOOP
END LOOP

the STEP value must be a positive value because of the effect of the
REVERSE clause...

i think it's just a matter of fixing gram.y, plpgsql.h (to add
another PLpgSQL_expr to the stmt_fori) and pl_exec.c (the way the
internal variable is incremented here makes me think that i wasn't the
first one with this idea)

i'm missing something? is "STEP" a good name for this? i will make a
try tomorrow

any ideas and suggestions are welcome...
