Dammit, i am on windows, DMD32 D Compiler v2.068.0
The name validator_t is not idiomatic in D. Something like
ValidatorFun should be preferred. Same for intReader_t;
ReadIntFun is probably preferred, or even IntReader (but that
would imply that it's a struct/class in my mind).
As for the actual use of partial, it's perfectly fine and
That should be it though... Could you try this minimal complete
test?

yes, it works likte that.
unique(arr) I get
Error: undefined
Well, if you don't type function names right, it will be hard
to help you.
oh, sorry. But I found out what I have been doing wrong besides
that.
arr.sort.uniq;
uniq(arr) or arr.sort.uniq; compiles but doesn't store it in the
arr array, I need to store it in a new one.
Are there any Phobos functions to check file permissions on
Windows and Posix? For example, I want to check if a file is
readable and/or writable in a cross-platform fashion. Does anyone
have an example?

I am considering using D for my latest project and there are a

- dynamic compilation of

You do. See docs for lpszMenuName field. GUI projects generated

Are you on 2.066 or older? Back then std.algorithm hasn't been
split into submodules yet. Just import std.algorithm then
instead of std.algorithm.comparison, std.algorithm.iteration,

Well, you can have an array of event factories:
IEvent function()[2] factories = [ factory1, factory2 ];
IEvent factory1() { return new Event1(); }
IEvent factory2() { return new Event2(); }
Then use enum for indexing:
IEvent e = factories[NumEvent1]();
