Environment/Map
[Base containers]

---

Detailed Description

A Text segment / Symbol table plus a Dynamic Array. Define key => data associations.

The map supports indexed access to keys and values and random access by key lookup. Once a key is created, it is never moved. This allows for compiling indexed accesses using lookup at compile-time only.

The VM creates its own environment, which is used to (un)serialize programs.

Data Structures
struct	_vm_dyn_env_t
Functions
word_t	env_sym_to_index (vm_dyn_env_t env, const char *key)
	Get index associated to symbol key. 0 means key dosen't exist in map.
const char *	env_index_to_sym (vm_dyn_env_t env, word_t index)
	Get key associated to index.
vm_data_t	env_get (vm_dyn_env_t env, word_t index)
	Get value at index.
void	env_set (vm_t vm, vm_dyn_env_t env, word_t index, vm_data_t)
	Set value at index.
