Agreed, but it does happen often that a language feature is later
superseded by a generalization thereof.
In this case it would be two features:
1. Allow to run arbitrary code at top level
2. Allow to pass a delegate to a function after the parameter list
void unittest (void delegate () dg)
unittest {
assert(true);
}
Would be lowered to:
unittest({
assert(true);
});
Then we also can easily support named unit tests:
void unittest (string name, void delegate () dg)
unittest("foo") {
assert(true);
}
Would be lowered to:
unittest("foo", {
assert(true);
});
I think it would be nice if D could get better at declarative programming.
