Hi.
Quote from CodeGear news
"circular uses clauses - why can't I declare two classes in two units
that refer to each other? Why doesn't forward declarations cope with
this? I've got this feature in C, C++ and C# why not Delphi?"
Because a Pascal compiler parses the interface section of an unit only
once, ...
That's a good question... Why can't FPC allow that either? I don't
know the internals of FPC, but can't FPC simply keep a list of used
units as it compiles, so it simply skips any later references. What is
the technical issue? I'm just curious here.
... and the interface section of an unit need to be parsed before used
by another one?
