Austin Clements 816e3da26d Make Value always represent an l-value and never a generic ... container for values. Instead of having one evaluator function that returns a generic Value, there is now an evaluator function for each generalized type that simply returns a native type. The compiler is more type-safe now because there are almost no type conversions at evaluation time and it's impossible to invoke a nil evaluator function during evaluation. This also makes ideals and pointers really clean. As an added bonus, expression evaluation should be faster because it doesn't require heap allocation for every intermediate value, type switches, or lots of conversions to and from Value. It also involves fewer function calls. R=rsc APPROVED=rsc DELTA=431 (280 added, 115 deleted, 36 changed) OCL=31705 CL=31709		2009-07-15 17:56:17 -07:00
