From: Francis De Brabandere <francisdb@gmail.com> Treat '(' after tEMPTYBRACKETS as an argument list opener in the lexer, so that expressions like GetArr()(0) or dict.Keys()(i) parse correctly. Also dereference VT_BYREF|VT_VARIANT results in vcall so chained indexing on call results works at runtime.
