[0.7] Add more informative error messages for unsupported new features #164

Closed hajduakos closed 4 years ago

hajduakos commented 4 years ago

There are some AST nodes where our visitor is not defined and gives an internal exception "Unhandled node (unknown)". We should give some more meaningful error messages (e.g., "Try-Catch is not yet supported") until we provide support. Such elements include:

OverrideSpecifier
TryCatchClause
TryStatement
IndexRangeAccess
StructuredDocumentation
