Extendo property feature plans

Summary

The __extendo_map_ property feature is planned which will extend
style properties with an arbitrary number of keys and values in a named
map.

Purpose

Extendo maps should be very handy for quickly creating similar selectors.

Example

Consider the following selector definition:

``js
_mixin_map_ : {
_fred_map_ : {
_background_ : '_xfff_',
_margin_ : '_0_'
},
_default_font_ : 'arial,sans'
}

_style_list_ = [
{ _selector_str_ : '#pcss-_switch_',
_rule_map_ : {
_color_ : '_x888_',
_font_ : '_default_font_',
__extendo_map_ : '_fred_map_'
}
}
];
`

The resulting CSS should be:
`css
#pcss-_switch_{background:#fff;margin:000;color:#888;font:arial,sans}
`

Requirements


The __extendo_map_ key (or more appropriate alternate) should be
reserved and will need to be interpreted as such:

`
Search for the specified anywhere in the cascade, and if found add the
properties of that map to the closure. If a map value for the provided key
(_fred_map_ in this example) is not found ignore this directive.
``

Status

This is currently WIP and is held in reserve. Prior implementation needs to be
rethought.
