Vlang has multiple methods of optional memory management. This should not be so hard to grasp, as this is the case for other languages too. Take Nim, for example. It has several: gc:refc, gc:markAndSweep, gc:boehm, gc:go, gc:arc, etc...

Vlang has both the options of Autofree and GC, or you can do it manually. As the language is still developing (like other languages such as Crystal, Odin, and Zig), users should know these memory management options are experimental and still being refined.
