nl_tokens: The runtime contains functions which must be converted into strings without any escaping at all . Yes this method of doing so is insane . But it works!
pl_tokens: function serializeVerbatim ( obj ) { let i = 0 const fns = [ ] let res = JSON . stringify ( obj , ( k , v ) => { if ( typeof v === 'function' ) { fns . push ( v . toString ( ) ) return ` ${ i ++ } ` } else { return v } } ) res = <mask> . replace ( / "__REPLACE(\d{1})" / g , ( m , v ) => { return fns [ v ] } ) return res }
