It is easy to avoid in a C-like language - simply require braces on "if" 
statements, or at the very least, require them when there is an "else" 
clause.  Most C coding standards and style guides make that requirement 
- not because the C compiler sees it as ambiguous, but because humans 
often do.  (Or they misinterpret it.)
