>From my experience anonymous functions are very useful when writing
event-based code, such as client-side event handlers for web browsers
with JavaScript, Expect event handlers in Tcl/Perl, and GUI event
handlers in any language. I think having a simple, readable way to
define anonymous functions in Python would allow writing more concise
and readable Python code for such applications, thus making Python an
even better Jack-of-all-trades.

However, even if it were easy to implement with clear, simple syntax,
I'm not sure this would be a good idea; I'd leave this to more
experienced language developers.
