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}

__a=__a${__a_n}
__a_n=$((${__a_n} + 1))
__l=0
for __v in "${@}"; do

__v=${__v#*=}
;;
