FPC already supports this (and I, for example, often use it).
Syntax is a += 1; however

"<<" is spelled "shl" in Pascal.

Now, this is IMHO a good point -- at least div= and mod=
operators should definitely be added to a set of "C-like" operators.
or= and= xor= would be good too, although I can see
some potential confusion regarding short-circuit behavior.

Heh, not even Perl 6 has these, and Perl 6 has *many* operators ;-)
