Added missing list type error check and line number fixes #246

Closed j14159 closed 6 years ago

j14159 commented 6 years ago

A missing error check in list typing caused failures with no helpful feedback for users. When fixing this, noticed that some list error messages all said the error was on line 0 which was just down to not supplying a proper line number when constructing the cons AST nodes.

Closes #223
