Afaik Delphi 7 is closed source, so inherently worse than any version of FPC.

You want to capture variable by value. For example lambdas in c++ have
special syntax to choose how to capture. By reference or by value.

Do you have any ideas how and why such behaviour implemented ?
Now I can answer my question myself. *Local variables of anonymous

This assumption is based on 2 points:
1.

Hi Vasiliy,
Just some additional info in case you are not aware.
Delphi implements the anonymous methods as interfaces, and that is how it
keeps them alive.
With best regards,

If the "x" is really located in the FrameObject and that object exists
only once then it is rather likely that the output of 'Before 123: '
is different from the output of 'After 123: ', right? Again I think
this is a bad thing...
