So, how will FPC distinguish the two []?
The only idea I have is to check whether the first identifier is a
attribute and if not handle it as a modifier (or if a comma is following
the first identifier).
pparser can't do that.
And I fear that this heuristic will lead to confusing error messages. I
hope there is a better way.
Delphi does not support it. It thinks it is an undefined attribute. So
IMO FPC's [] modifier should be disabled in mode delphi+delphiunicode.
So the problem will only happen in mode objfpc or when the user
enable the modeswitch prefixedattributes.
I think that prefixedattributes should simply disable the use of proc
modifier []. The probability of having code that needs both is almost zero,
the [] syntax is very old and almost not used.
Mode Delphi(Unicode) enables prefixedattributes, all other modes need an
explicit modeswitch to enable it.
Let's keep it clear, simple and unambiguous.
Michael.
