[fpc-devel] Some thoughts on multi-line string support, and a possible syntax that I think is perfectly clean and Pascal-ish.

Sure I meant with that, if a new scheme would be introduced to make
multiline strings easier, i would prefer such operator, then as real
compiler operator also for constants and so on. Mine is just a
workaround. (the operator would also automatically select the right line
ending, mabye defined together with decimalseparator in formatsettings)

real multiline strings, I do not like, because they look ugly in a well
indented code... so your initial example taken would have an awful lot
of spaces in front of all lines, exept the first one.
