Why should there be special syntax just for repeating a block N times?
There's a general purpose for-loop which performs iteration. Why do you
need special syntax to do what it already does?

The 'i' is superfluous. Why not:
for 10:
(In my own syntaxes I use (actual example):
to 64 do
table append:= nextbyte(fs)
od
Python equivalent:
for i in range(64):
table.append(nextbyte(fs))
The range object isn't really necessary, and the 'i' variable doesn't
need to be exposed (as a programmer-accessible, reference-counted variable).
The 'to' construct I also implemented with a single very fast byte-code,
executed once per iteration.)
