Hi, I have a few proposals/questions related to boost::tokenizer: - the first template parameter of char_separator and other tokenizer functions could be defaulted to char to save typing and make it consistent with the defaults of tokenizer; - making the constructor of char_separator and other tokenizer functions non-explicit would allow for less verbose construction of a tokenizer; - the docs state that char_delimiters_separator is deprecated in favour of char_separator. Are there any plans to actually drop the former and change the default for the template parameter of tokenizer to the latter? I guess this might be controversial because interfaces and semantics of the two differ, so maybe providing a new template, say string_tokenizer, is a good idea? Combining the first two points, the following: auto t = boost::tokenizer( str, boost::char_separator<char>("-;|")); could be written more conveniently as: auto t = boost::tokenizer>(str, "-;|"); and adding the third point it would become: auto t = boost::string_tokenizer<>(str, "-;|"); which is IMO a significant improvement. Any thoughts? Best regards, Robert
