RE: C# and Lua

[Sean Middleditch <elanthis@...>]

It really shouldn't be much different than writing Lua in C, no?  I
mean, you could have a .NET type/class for a "Lua Value", which used the
native String/int/float/array/etc. types where appropriate.  It could
allow dynamic changing - assign an array type to the type (value.assign
(array)) and the class stores the array and marks itself as an array
type.  Assing a string to the same variable/member/etc. (value.assign
("a string"))) and it would store the string, and mark itself as a
string type.

The method could be overloaded to react differently based on the type. 
For example the + operator could look at the types involved - if
strings, do concatenation; if numbers, just add; if tables, call a
method in the table, and so on.

It won't be able to optimize as well (for example, know to just call
string concatenation at compile time, versus having to check types on
run-time) but it would still work, I would think.

Or am I missing some important fact here?  (as usual) ^,^
