Sequence code on Page 42 unable to compile

[andrewgohlk]

The below sequence code on Page 42 is not able to compile in nim 2.0:

let list = @[4, 8, 15, 16, 23, 42]
for i in 0 .. <list.len:
stdout.write($list[i] & " ")

---

Encountered the following error:
D:\nimTest\seqTest.nim(2, 15) Error: type mismatch
Expression: <=len(list)
[1] len(list): int

Expected one of (first mismatch at [position]):
[1] proc <=(x, y: bool): bool
[1] proc <=(x, y: char): bool
[1] proc <=(x, y: float): bool
[1] proc <=(x, y: float32): bool
[1] proc <=(x, y: int16): bool
[1] proc <=(x, y: int32): bool
[1] proc <=(x, y: int8): bool
[1] proc <=(x, y: pointer): bool
[1] proc <=(x, y: string): bool
[1] proc <=(x, y: uint): bool
[1] proc <=(x, y: uint16): bool
[1] proc <=(x, y: uint32): bool
[1] proc <=(x, y: uint64): bool
[1] proc <=(x, y: uint8): bool
[1] proc <=[Enum: enum](x, y: Enum): bool
[1] proc <=[T: tuple](x, y: T): bool
[1] proc <=[T](x, y: ref T): bool
[1] proc <=[T](x, y: set[T]): bool
[2] proc <=(x, y: int): bool
[2] proc <=(x, y: int64): bool

========================

However, removing the space after the '..' fix the issue.

let list = @[4, 8, 15, 16, 23, 42]
for i in 0 ..< list.len:
stdout.write($list[i] & " ")

Before nim 1.4.0 (not sure of the exact version), the operator was .. and < was a template symbol for the substraction by 1.
This is true for all listings in Nim in Action and most of ancient Nim code.
