           Summary: Remove EscapeString literals.
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


The ability to create escape strings is a waste of the backslash character.
"hello world" \n
is not sufficiently superior to
"hello world\n"

Try that again with several different \ things in the string. it quickly get
unreadable.

Can you provide an example? Whenever I read a separated \n or \t it seems like
it doesn't belong to the string and it confuses me, it makes it more
unreadable.

Just to clarify, I /don't/ like the suggestion.

C has got by with it perfectly well for an awful long time.

So has virtually every other language.  I don't think I have *ever* seen the
backslash string literals used in any D source.  I doubt most people even know
of their existence.

I use them often when for literals of length 1. E.g.

return stringVar ~ \n;

That's no where near worth the price of giving up a whole symbol in my opinion.

But I think such a change should probably be bundled with an agreement on what
to actually do with the freed up character.  If the syntax is removed and D
never does anything with it, then that's a waste.  \n is not useless, it's just
an underperforming use of \.  What to do with it should be decided upon before
giving it the axe.  (lambdas were suggested somewhere).

I also don't like these escaped chars hanging around on their own.
Lambdas are expected to be just a minor syntax sugar for delegate literals:
return statement and parameter types will be removed.

It's a good idea to remove them. The feature didn't turn out to be interesting
or useful, and it's time to clean out some detritus.
