Changes for version 0.007

  • Alpha release. New features/fixes:
  • Added the RegExp constructor and RegExp.prototype.exec
  • Added the rest of the string methods
  • Added the Boolean, Number and ReferenceError classes
  • Added the Math object
  • Fixed 'return' without an argument, so it returns undefined, rather than a null Perl string (which was causing weird errors elsewhere).
  • 'break' called from within a labelled statement was produc- ing warnings (fixed)
  • 'throw' without an argument now throws undefined, rather than 'Died at /usr/local/lib/perl5/5.8.8/JE/Code.pm line 387'
  • 'continue' now works with a do-while loop
  • instanceof now works instead of just dying
  • Assigning to a writeable property used to overwrite the dontenum attribute and make the property enumerable (fixed)
  • Fixed lvalues such that 'null.var = val' no longer creates a global property. 'null.var' in void context now throws a TypeError.
  • Fixed the null and undefined classes, so they don't try to rebless the same scalar as each other.
  • Fixed the boolean class's to_string method, so it no longer gives 'true' for false and 'false' for true (!).
