Memory only variables

[vantreeseba]

What it would do:

Allow users to access tokens that exist only in memory, setting some placeholder for the token to get it from.
This would throw an error or warning if the token does not exist in memory.

Example:

"This is a #name:_# from memory"

Implementation:

Set some setting or default token name that means it's a placeholder for a token that should not error when used.
Can check if it is a memory token accessing that, and if it matches, throw an error when the "throwaway" token has no associated memory value.

Make this look like #some_grammar:some_stored_var# and when in memory only, do #:some_var#
