[armedbear-devel] [RFC] Support for 'synchronized' blocks in Lisp code

I propose that we introduce a WITH-EXCLUSIVE-ACCESS form in the EXT package, which takes 1 argument (the second value) and a body (the third value). The form makes sure that the body is evaluated as if it had been called with:

synchronized (arg1) { body-to-evaluate; }

Except that it implements this in Lisp. This way, our Lisp<>Java interoperability would increase. It would also be an efficient way to guarantee exclusive access when modifying a cross-thread shared resource (such as generic functions).

Comments?

Bye,

Erik.
