parsing dash '-' in json path

[romange]

Seems that jsoncons rejects '-' when it appears in field names. Is it by design? I know it's still possible to use quotes for referencing fields but unfortunately we get our jsonpath expression from a user that uses dashes and preprocessing the string before passing it further to jsonpath::make_expression is complicated.

By design, see jsoncons JSONPath. Allowing hyphens in bare property names conflicts with allowing unary minus and subtraction in filter expressions.
