I know it looks silly but if you make that:
printers[i] = (int i) { return () { write(i); }; }(i);
it will do what you want.
This is something that used to be common in javascript, write a
little function that passes the capture-by-value args and returns
the lambda you actually want and call it immediately.
That extra layer causes the compiler to create a new copy of the
capture variables snapshotted in time.
