Others, like assignments with invalid targets, are caught in the code generation phase. The compiler package catches some errors in the transformer module. But it seems clearer to write checkers that use the AST to detect errors. i����( t astt walkc C s t | � } t | | � | j S( N( t SyntaxErrorCheckerR t errors( t treet multit v( ( s% /usr/lib/python2.7/compiler/syntax.pyt check s R c B s, e Z d Z d d � Z d � Z d � Z RS( s+ A visitor to find syntax errors in the AST.c C s | | _ d | _ d S( s� Create new visitor object.
