pure:

void main() {

float x = vec.len2();
writeln(x);
x = vec.e();
writeln(x);

I get error by compiler when i build this:
main.d(30): Error: no property 'len2' for type 'Vector!float',
did you mean 'len'?
In dmd 2.067 is normaly.
is it Bug or enhancements?
Does not work in 2.067 for me.
Btw. you do not need to do this:
alias selftype = Vector!T;
You can just use Vector, or:
alias selftype = Vector;
if you prefer selftype as a name.
