It’s really unlikely we would use { } because one day we will want to implement array literals. You know one time I messed with the server tag code in the parser so that reverse server tags could be used for this ;-)

That of course would never pass the sniff test!

Anyway, if I might propose an alternative of allowing the line continuation char (which happens to be escape) within strings. The sequence \ & return & <any number of spaces> would be replaced with just return in the string.

Something like this:

put “foo\
         bar”

would put:

foo
bar

Of course if you need leading whitespace then that’s a bit trickier but the above could be relatively easily implemented in both the script editor and the parser.
