Uri class and parser

[Mike van Dongen]

Been thinking about this for a while now, but I can't decide 
which one I should choose.

Currently there is a class URI which has an static method 
(parser) which returns an instance of URI on success. On failure 
it will return null.

I agree with Jens Mueller on the fact that URI should be a struct 
instead of a class. But then I won't be able to return null 
anymore so I should throw an exception when an invalid URI has 
been passed to the constructor.

I'm not sure if this is how problems are being handled in phobos.


Something entirely else is the CTFE compatibility of URI. At 
first I though that because a new instance of URI can be created 
as a const, it would be evaluated on compile time.
This is part of how I test CTFE at the moment:

const URI uri36 = URI.parse("http://dlang.org/");
assert(uri36.scheme == "http");

I tried changing 'const' to 'static' but that resulted in an 
error.
(_adSort cannot be interpreted at compile time, because it has no 
available source code)

Now I'm not sure anymore how to test if my code meets the CTFE 
requirements.


I hope someone can shed some light on my problems and help me 
make a decision.
