Why does Phobos use enum for constants?
Why does Phobos use enum to define constants? For example, in std.math:
enum real E = 2.7182818284590452354L;

integer to string conversion in D
How in D would I cast integer to string?
Something like
int i = 15
string message = "Value of 'i' is " ~ toString(i); // cast(string) i - also does not work

Binary Search in D 2.0 (Phobos)?
Is it just me, or is there no binary search function in Phobos? I have a pre-sorted array that I want to search with my own comparator function, but I can't find anything in std.algorithms or std.containers.

What is the current status of D standard libraries?
There are two of them Phobos and Tango.

If so, when will it happen?
