Well, it's not nearly as hard to read, for one thing. But seriously,
the use of lambda functions (google it) can provide a degree of
flexibility in code and help prevent coding errors. For instance, to
add the arctan() to your example you'd have to add a new line to the
option control, then add a new case statement to the switch construct
in the mouseUp handler. Possibly you could make a mistake when cutting
and pasting, forgetting to insert a break statement, etc. Using the
redirected form all you'd need to do is add the new line to the option
control.
