for loops restricted to int only
f#

I've noticed that if I write

for i = first to last do

... i ...

then first and last have to have type int; they cannot, for example,

have type uint8 or int16. Is this a deliberate restriction, or

just an oversight? This restriction can require a lot of casting:

for i = int(first) to int(last) do

... uint8(i) ...

One workaround is to write

for i in {first .. last} do

... i ...

but I'm not sure if the resulting code is as efficient.

.

They can have different number types

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

 

for i in 0s .. 99s do //int16
  print_any i


for i in 0 .. 99 do //int
  print_any i

for i in 0L .. 99L do //int64
  print_any i

for i in 0.0 .. 1.0 .. 10.0 do //float ... to de deprecated ?
  print_any i
