^this!

In garbage-collected languages, please give me gradual / optional annotations that permit deterministic fast freeing of temps, in code that opts in.

Basically to relieve GC pressure, at some modest cost of programmer productivity.

This unfortunately makes no sense for small bump-allocated objects in languages with relocating GC, say typical java objects. But it would make a lot of sense even in the JVM for safe eager deterministic release of my 50mb giant buffers.

Another gradual lifetime example is https://cuda.juliagpu.org/stable/usage/memory/ -- GPU allocations are managed and garbage collected, but you can optionally `unsafe_free!` the most important ones, in order to reduce GC pressure (at significant safety cost, though!).
