I just had an idea come to my head - what if Lazarus would handle
the tiers of try for us ? Maybe it should be a feature of the code editor,
to convert
try
try
try
code block 1;
except
code block 2;
end;
finally
code block 3;
end;
except
code block 4;
end;
into
try
code block 1;
except
code block 2;
finally
code block 3;
except
code block 4
end;
and variations thereof; Then no compiler changes are necessary.
Lazarus already has the 'collapsible code blocks', and this is not much
different. I'll post this idea to Lazarus list.
cheers,
