I guess I’ll try asking this again: How come Red doesn’t have a GC? If Red doesn’t have free, does it just leak memory?

First version of GC (and maybe some memory-management natives) will be integrated in 0.6.4 release, meanwhile there's some bag of tricks and conventions (`/into` refinement, creating series with `make ...`, etc) you can use to avoid additional allocations (almost) entirely.

Yes. Last I checked, it just leaks memory. It doesn't have GC because it's a new language that is under heavy development. It doesn't have a lot of things that any sane language must have before 1.0. Give it time.

Like C or like Java with the GC turned off?

C has alloc and free. Red is supposed to be garbage collected, so there's no free.

How come Red doesn’t have a GC then? If Red doesn’t have free, does it just leak memory?

GC will come. It just hasn't been needed yet for Red to continue its own development. If you write in Red/System, the C level dialect, you have `free`.

It's like there's an echo in here.
