If by "arrays (as opposed to vectors)" you mean N dimensional (as opposed to 
just one dimensional), then yes.  No such data type is built in, but you're 
free to build one and the Fortran-like syntax will work just fine.

Nope.  #1 currently expands to

    array put(5, 7, 1.47)

and will expand to

    array op__setitem(5, 7, 1.47)


>array op__getitem([6,9])

Nope.  #2 currently expands to

    foo := array get(6, 9)

and will expand to

    foo := array op__getitem(6, 9)
