What is the correct format for named character entities? According to
the online specs, I should be able to write:

	dchar ch = '&';

But gdc-4.6.2 refuses to compile this; apparently it wants:

	dchar ch = '\&';

Which is right??

The latter is right. The spec must be implying the \ character as all of 
the other special character syntaxes use it. One of the reasons is that 
character are specified the same way in strings. So "&" is 5 
characters as written. Again, a \ character is required to distinguish 
it as a single character literal.

Hmm, then the specs need to be fixed, since currently it says:

	EscapeSequence:
	    \'
	    \"
	    \?
	    \\
		[...snip...]
	    NamedCharacterEntity

And:

	NamedCharacterEntity:
	    & Identifier ;

Somewhere in there a \ needs to be included.
