  2. Support quoted symbols 

    A JSON key (referred to as a symbol by the filtrex grammar) is a string
that may contain operators. For example, a JSON key containing a dash is
valid but will be parsed as an arithmetic operation:

    {"country-code": "US"}
    compileExpression.parser.parse("country-code == \"US\"")

Results in:

    country - code == "US"

Indicate a literal symbol by using a single quote:

    compileExpression.parser.parse("'country-code' == \"US\"")

Similar to double quotes in strings, single quotes in symbols are
not valid: 'invalid\'symbol'

  3. Support regular expression matches 

    Introduce an operator (~=) to perform matches using regular expressions:

    {country: "US"}
    country ~= "^(US|CA)"
