• Pavel Minayev (10/10) Dec 29 2001 D doesn't allow to convert integers to pointers. This is great
• Walter (5/15) Dec 29 2001 Hmm, it won't let you do a cast, a-la:
• Pavel Minayev (10/13) Dec 30 2001 Sorry, my fault. The code looked like this:

explicitly defined integer value to be of type char*... not
only these, but there are some constants like IDI_APPLICATION
that also should be char* while having the very exact value;
unfortunately, I don't see any way to do this in D, currently,
other than making them all ints and let user do the proper
casting where necesarry. Walter, do you have any suggestions
how to do this in other way?

Sorry, my fault. The code looked like this:

    const char* a = cast(char*) 666;
    ...
    // a few hundred lines later
    const int b = a;

For some reason, compiler says "unable to cast int to char*"
(or whatever it was) pointing at the declaration of a rather
than b, even though the latter is wrong...
