Name resolution bug

The sample code above is the result of a two-step transpilation (TypeScript, Google Closure with advanced minification): mod.ts → mod.js → mod.min.js.

The original TypeScript code is

class SHT1x {
      constructor( options: SHT1xOptions, onReady?: () => void ) { … }

      // Propiatary CRC checksum calculation for SHTx - has nothing to do with a real CRC calculation!
      private static calculateCrcChecksum( data: number, initialCrcValue: number ): number { … }
}        

I can remove the "static" keyword but it wouldn't be 100% semantically correct because there could be more instances of SHT1x and the checksum method does not need any instance variables. Nevertheless it's a good workaround.

Otherwise it would be good to know the origin of the problem. So the current Espruino rule to work around the bug is: Don't use class methods at all?

I have to check other modules I contributed:
