Bultins .reverse and .sort are likely going to be removed soon.

[Stefan Koch via Digitalmars-d-announce]

Hi guys,

I just finished the PR to remove the builtin array properties 
.sort and .reverse.

while the dmd changes were trivial fixing all the broken tests 
were not.
Even tests that were supposed to call std.algorithm.sort turned 
out to use the property by accident; (because of a small error 
which caused the sort template not to instantiate).

If you do have code which still relays on this, please update.

Cheers,
Stefan
