Hi,
This pattern is not inherently efficient. Why should it be ?
It is not efficient, because of the pointless instruction!
I am not speaking of the current FPC implementation. It may well be that
the
code is not most optimal.
I am asking, why do you think *this pattern* (of always returning self)
should be inherently more efficient ?
The pattern definitely has its uses. E.g. in the user space of our
operating system at work we have a StdOutPrinter class that is used like
this:
=== code begin ===
StdIO::stdOutPrinter()->out("Helllo World ")->out(42)->out("
")->hex()->out(42)->line();
Call me old-fashioned, but I much prefer
With StdIO::stdOutPrinter() do
begin
out("Helllo World ");
out(42);
out("");
hex();
out(42);
line();
end;
I see no point or gain in the "fluent" code.
Michael.
