The
class << xhas no implementation and returns no statement ASTs. This caused a crash in the statementSeq(lastStmtAsReturn(stCtx.getText, stAsts.head))sincestAstswas a empty list.Put a check for the list size to avoid a crash. Wrote a test for the same.
A proper implementation of
class << xwill avoid this issue. However, that will be in a separate PR. This one only avoids the crash.@xavierpinho
