There seems to be an error in Pie.g, where it reads
atom[boolean defer] returns [Object value]
: INT {if (!defer) $value = $INT.int;} // return int value
| ID {if (!defer) $value = interp.load($ID);} // look up value
| CHAR {if (!defer) $value = new Character($CHAR.text.charAt(1));}
| FLOAT {if (!defer) $value = new Float($FLOAT.text);}
| STRING {String s = $STRING.text; if (!defer) $value =
s.substring(1,s.length()-1);}
| structscope[defer] '.' ID // field access
{if ( !defer ) $value = interp.fieldload($structscope.value, $ID);}
| 'new' ID {if (!defer) $value = interp.instance($ID.text);}
| '(' expr[defer] ')'
Should the last line be
| '(' expr[defer] ')' {if (!defer) $value = $expr.value;}
?
