in reply to Implementing (elisp-like) buffers in Perl 6: how to do buffer-localisation of arbitrary package variables?
Could you have an on-buffer-change hook of some sort that accesses a data structure keeping track of which variables were buffer-local to which buffers and swaps their values in and out appropriately?
That is, something like (quite untested):
sub onBufferChange { my ($from, $to) = @_; for my $scl (values $from->{locals}) { $$$scl[0] = $globalLocals{$$scl[0]}[1]; } for my $scl (values $to->{locals}) { exists $globalLocals{$$scl[0]} or $globalLocals{$$scl[0]} = [$$scl[0], $$$scl[0]]; $$$scl[0] = $$scl[1]; } }
I have the feeling I've missed the point...
