"warning - array 'length' hides other 'length' name in outer scope"
...
"The warning can be resolved by:

   1. Renaming the outer length to another name.
   2. Replacing the use of length within the [ ] with a.length.
   3. If length is at global or class scope, and that was the one intended to be used, use .length or this.length to disambiguate.

Some proposed language solutions are:

   1. Make the length a special symbol or a keyword instead of an implicitly declared variable."

You've just added the $ notation, yet you haven't mentioned it here. Simply because it's a trial feature, and the page might end up out of date if you decide to get rid of it?

And IMM making length a keyword wouldn't be the Right Thing - we'd lose the ability to use this name for a property in container classes.

Excellent!

I think this is a bug:

//-----------------------------------------------
int bar() { return 0; }
bool foo() { return bar()==0; }
void main() {}
//-----------------------------------------------

warning - test.d(2): implicit conversion of expression (bar == 0) of
type int to bit can cause loss of data

Same happens if bar is instead a variable, but not if it's a constant.

Notice, however, that this doesn't produce any warning:

int foo() { return null?0:1; }

But this does:

bool foo() { return null; }

Oh, Christ Almighty.  Coming from a basic background, this is going to look confusing.  Strings everywhere.

He is indeed. Please don't resort to profanity.

We've decided to placate Believers, Agnostics and Atheists on this ng by referring to Bob, who may be what/whomever you choose, or your reader interprets. ;)

And people coming from BASIC would think that it is a string :-)

Great, now I can start using all weirdo names! :-)

Well, when GDC catches up with DMD again that is...
(currently gdc 0.10 is at dmd 0.110, feature-wise)

Using "dot" like that is already the global scope resolution operator.
