Euphoria implementation
There has been talk of changing Euphoria. For me it is better to
make functions cheaper or at least less time consuming ot execute if
possible because it means that less programmers will hvae to inline
things and forgo using functions in many places.
In the Performance documentation it says:
It is cheaper to copy to a temporary modify the temporary and then
assign the temporary variable back to the original. See the part
on indexing. It goes on to say that the line
xi = x[i]
"only copies the pointer..."
Inspite of xi being modified later Euphoria doesn't make another
copy of xi which is good as in this case x[i] will be reassigned
xi.
I think it is a natural extension of this idea to have statements
like this: "n = foo(n)" pass by reference. As it makes
no difference to the functionality of the program. Ofcourse things
like "x = foo(n)" would be pass by value as it is now. The benifit
is that many programs would get faster for nothing.
