Re: Constraints patch - help?

[Asko Kauppi <askok@...>]

I've done that, of course. :)

The issue is, in larger programs its really benefitial to have the  
_option_ of using type constraints on your variables, values, and  
return values.  Doing them integrated with the syntax simply hides  
them more from the eye than doing 'assert' everywhere.

Perhaps people don't see the urge for this; I wouldn't either in  
smallish programs.  But let's consider things s.a. svn 2.0  
considering use of Lua (without them actually _knowing_ about the  
language beforehand!) as part of their core implementation. If I were  
doing such code, I'd like to have them checks!
