Postfix string literal alternative suggestion

[Edward Diener]

The string literal in D can have a postfix character of 'c', 'w', or 'd' 
for specifying the type of the literal. This notation is in the same 
spirit as the C++ prefix of L"..." to specify a wide character string. 
Such syntax does not play well with templates based on a character type.

I would like to suggest instead the use of a cast(type) expression for 
string literals, perhaps something like 'string_cast(type)"some string 
literal"' where the type would have to be char, wchar, or dchar. This 
says to treat the literal as a particular type and would be a 
replacement for "some string literal"c|w|d notation. The reason I think 
my suggestion is superior is that one may have a template class or 
function in which one of the template parameters is a character type and 
then one can easily specify the template type using the notation 
suggested by me to coerce a string literal to the preferred type without 
having to know the type of the template parameter.
