This is a lexical issue. The lexer is greedy, so yes the tokens would be 
"5." "<" ".4"[1]. I don't believe this lexical issue would be a real 
problem in real code. For instance the expressions "f<.4" and "i.<.4" 
would both work as expected.


[1] >> and >>> are the only real oddities in Java. As well as being 
double and triple close of generics, they are some obscure operators 
that don't really belong in Java (IMO).
