special no inheritance mark

[jscotka]

Cretead improvement, to have some items without inheritance in tree

• uses special characted ! at the end of key e.g. key!: some value

There are two possible solution:

already implemented in two inclueded commits

• let special character at the end, so that key is key! in data.
  • PROS:
    • easy to find the item
    • easy to search
    • easy to lint
  • CONS:
    • special character may be confusing comparing to removing + and - elements from final tree
    • may contain key and key! together - may confuse users
• remove special character and let it as normal key
  • PROS
    • easier for user to understand it, it is special char, and will be removed
    • automatically it solve also removing keys as side effect, so it stop inheritance, if there is defined X in parent and in some child X! then next child will have X undefined
  • CONS
    • not so clean from perspective that you may mix X and X! so that you will use these inherited and uninherited items together and not easy to search for special key with X! to know that it is defined on specifix place (may be workarounded but not nice)
    • When user remove ! it will behave in same way, so that tool has to know, that in node there is special attribute what contains, these unique keys for node.

@psss @jscotka We have implemented inherit: false . Should this be dropped?
