Syntax:

	array=(1 2)
	array[0]=3
	push ${array} 4
	# Instead of Bash's ${array[@]} or ${array[*]}:
	string=$(join ', ' ${array})
	value=${array[0]}
	unset array[0]
	unset array
	array=(1 (2 3) 4)
	array=(one=1 two=2)

Compiles to:

	__a_new __r0 1 2
	array=${__r0}
	__a_set array 0 3
	push ${array} 4
	string=$(join ', ' ${array})
	__a_get __r0 array 0
	value=${__r0}
	__a_unset array 0
	__a_new __r0 2 3
	__a_new __r1 1 ${__r0} 4
	array=${__r1}
	__a_new __r0 one=1 two=2
	array=${__r0}

eshrt functions:

	__a_n=0  # malloc-like, how do we free?
	__a_new()
	{
		__r=${1}
		shift 1
	
		__a=__a${__a_n}
		__a_n=$((${__a_n} + 1))
		__l=0
		for __v in "${@}"; do
			case ${__v} in
				*=*)
					__k=${__v%%=*}
					__v=${__v#*=}
					;;
				*)
					__k=${__l}
					;;
			esac
			eval "${__a}__${__k}=\${__v}"
			__l=$((${__l} + 1))
		done
		eval "${__a}_l=\${__l}"
		eval "${__r}=\${__a}
	}
	__a_set()
	{
		__a=${1}
		__k=${2}
		__v=${3}
	
		if ! eval "\${${__a}__${__k}+:}"; then
			eval "${__a}_l=\$((\${${__a}_l} + 1))"
		fi
		eval "${__a}__${__k}=\${__v}"
	}
	__a_get()
	{
		__r=${1}
		__a=${2}
		__k=${3}

		eval "${__r}=\${${__a}__${__k}}"
	}
	__a_unset()
	{
		
	}

libesh functions:

	push()
	{
		__a=${1}
		__v=${2}
	
		eval "__l=\${${__a}_l}"
		if ! eval "\${${__a}__${__l}+:}"; then
			eval "${__a}__${__l}=\${__v}"
			eval "${__a}_l=\$((\${__l} + 1))"
		fi
	}
	split()
	{
	}
	join()
	{
	}

pop, shift (name collision), unshift, slice, keys, etc.
