Object Member Access Operations
===============================

Lvalue Assignment
-----------------

Implementation:

    # High level
    array_set ${obj} mbr ${val}
    # Low level
    eval __arr_${obj}_mbr'=${val}'

Syntax:

    obj->mbr=${val}

Explanation:

`->` dereferences/expands `obj` and accesses the `mbr` lvalue, as in the
following (unsupported) syntax: `${obj}.mbr=${val}`.

Rvalue Expansion
----------------

Implementation:

    # High level
    array_get ${obj} mbr
    val=${retval}
    # Low level
    eval 'val=${'__arr_${obj}_mbr'}'

Syntax:

    val=${obj->mbr}

Explanation:

`->` dereferences/expands `obj` and accesses `mbr`, then `${...}` expands its
rvalue, as in the following (unsupported) syntax: `val=${${obj}.mbr}`.

Rvalue Call
-----------

Implementation:

    # High level
    array_get ${obj} mbr
    ${retval}
    # Low level
    eval "\${__arr_${obj}_mbr} ${obj}" 'arg'

Syntax:

    ${obj->mbr} arg

Explanation:

`->` dereferences/expands `obj` and accesses `mbr`, then `${...}` expands its
rvalue, as in the following (unsupported) syntax: `${${obj}.mbr}`.

Class Member Access Operations
==============================

Lvalue Assignment
-----------------

Implementation:

    # High level
    array_set Cls mbr ${val}
    # Low level
    eval __arr_Cls_mbr'=${val}'

Syntax:

    Cls::mbr=${val}

Explanation:

`::` accesses the `mbr` lvalue of `Cls`.

Rvalue Expansion
----------------

Implementation:

    # High level
    array_get ${Cls} mbr
    val=${retval}
    # Low level
    eval 'val=${'__arr_Cls_mbr'}'

Syntax:

    val=${Cls::mbr}

Explanation:

`::` accesses the `mbr` member of `Cls`, then `${...}` expands its rvalue.

Rvalue Call
-----------

Implementation:

    # High level
    array_get ${Cls} mbr
    ${retval}
    # Low level
    eval "\${__arr_Cls_mbr} Cls" 'arg'

Syntax:

    ${Cls::mbr}

Explanation:

`::` accesses the `mbr` member of `Cls`, then `${...}` expands its rvalue.
