Agreed, awfuly crippled design for a language with Thread-local by

Looks like we have 'oh my god, what were they thinking' moment here.
The synchronized class feature was copied by Walter from Java while he
at the time had only little understanding of multithreading. The
thread-local by default notion was added much later.
Indeed we'd design things very differently if synchronized came about
later. The design of "synchronized" described in TDPL and not yet
implemented is a conciliation of the two.
If anything I'd rather re-implement the whole v-table infrastructure via
mixins, templates & friends.
Could you please elaborate how that would help multithreading?
Andrei
The whole concept of synchronization needs to be ripped out of Object
with *extreme prejudice*. We have core.sync.mutex for a reason.
I think the vtable infrastructure as templates/mixins is an orthogonal
point.
