default(T) ?

[Andrew Davey]

Does nemerle have an equivalent of C#'s default(T) ?

Look here:
http://rsdn.ru/forum/nemerle/2281812.all.aspx

In short.
Just use mutable keyword:

mutable a : int;


Or if you want explicit expression use
Nemerle.Extensions;DefaultValue:

using Nemerle.Extensions;

module Program
{
F[T](a : T) : void
{
def i = DefaultValue(T);

Use macro Nemerle.Extensions.DefaultValue(T).

PS

I think we mast add keyword "default" in Nemerle.Core namespace/

I remember that I intentionally didn't add 'default(T)' to
Nemerle.Core, since so far we don't use this keyword and this would be
the only place we need it. IMHO default(T) is relatively rarely used
and it is perfect candidate to just express it as library macro call,
not a builtin.

I answer this question already in 100-th time.

A C# programmers use this intrinsic function very often.

I think, that we should support the default(T) to not confuse beginners.
