Defining constants in global scope

[Thomas Sondergaard]

irb(main):001:0> module AModule
irb(main):002:1> end
=> nil
irb(main):003:0> AModule::AConstant = 1
=> 1
irb(main):004:0> ::AnotherConstant = 0
SyntaxError: compile error
(irb):4: syntax error
::AnotherConstant = 0
^
from (irb):4
irb(main):005:0>

Why can't I define a constant like this?

Cheers,

Tom

Why can't I define a constant like this?

My guess is, and I'm new to Ruby so I'm probably wrong, that you first
need to open the "global" Module or class for which you want to define
the constant for. In this case this would be the Kernel module.

So something like:

Kernel::MyConstant = 1

irb(main):004:0> ::AnotherConstant = 0
SyntaxError: compile error
(irb):4: syntax error
::AnotherConstant = 0
^

It works with latest CVS head.
