oops! Sorry about the mix up on the last post :( Anyway, I'm already aware that I'm a bug on the planet Earth, yet I'm not subject to any fixing here...but I must say that my wife has been doing a pretty good job on debugging me so far. (Still, I don't think there's anyway a total fix can be applied to me this far into the current life cycle.) :)) Don't mind me...life and application software just seem very similar at this point.

Why do you even need this?  Or is it just something to show the bug with?  :)

> #     writefln("length=%d", cast(long).length(toString(min(10,9)))); 
Here's your error right here...  It should be:
# writefln("length=%d", cast(long)(toString(min(10,9)).length));

Or:
# writefln("length=%d", cast(long) length(toString(min(10, 9))));

Only thing is, since '.' is supposed to double as the module-scope operator, the first version /should/ work.  But I think its trying to call it as a property-function (or whatever we ended up calling these things) rather than a module-function.  Oddness.

Only to show that there's a bug...otherwise the code is pretty useless. :)

Like you pointed out, the module-scope '.' should work even in this code, and this is exactly the error I wanted to point out.

I found this error while writing some code where a wrote my own min() function and added a '.' because I had imported std.math, thinking std.math would have it defined as well. But to my surprise std.math doesn't, and the error occured when I tried to compile the code...so I decided that I should take the time to post a simple clear example of the problem. Overwise it may not be found and fixed anytime soon. <g>
