A concatenation of the *binary* "<" or "<<" operators, into "<<<<...", 
doesn't make sense (syntactically), so that the scanner could generate 
an appropriate error token (or message). Just as in handling "." .. 
"..." tokens, where more than 3 consecutive dots also are definite 
syntax errors. AFAIR a check for an fourth dot is not performed by the 
scanner, and seems not required because the resulting parser error 
message is sufficient. But a check for a third "<" definitely should be 
added to the scanner, so that a more specific error message can be issued.
