Previously, bindings were parsed as the combination of two tokens: '$' IDENT This meant that using a keyword as variable name (e.g. $then, $label) did not work. Attempts were made to allow $keyword to work by adding some '$' Keyword rules in the parser, but this did not allow $keyword in all places: jq --arg label foo -n '$label' # ok jq -n '"foo" as $label | .' # error Treating $foo as a single token is much simpler, in my opinion. This patch also changes how LOC is lexed: "$__loc__" instead of as "__loc__" that gets combined with '$' in the parser. This patch also disallows having spaces after '$' when recalling a variable `$ foo' since that was probably just an unintentional side effect of the implementation, and it was not documented. Fixes #2675
