ruby send method passing multiple parameters
...method-name clashes”
Black also suggests wrapping calls to __send__ in if respond_to?(method_name).
if r.respond_to?(method_name)
puts r.__send__(method_name)
else
puts "#{r.to_s} doesn't respond to #{method_name}"
end

What's the difference between echo, print, and print_r in PHP?
...ess the same; they are both language constructs that display strings. The differences are subtle: print has a return value of 1 so it can be used in expressions whereas echo has a void return type; echo can take multiple parameters, although such usage is rare; echo is slightly faster than print. (P...
In Python, if I return inside a “with” block, will the file still close?
....
It is also mentioned in one of the examples of PEP-343 which is the specification for the with statement:
with locked(myLock):
# Code here executes with myLock held. The lock is
# guaranteed to be released when the block is left (even
# if via return or by an uncaught exception).

Why return NotImplemented instead of raising NotImplementedError
...hould ask someone else to satisfy the operation. In the expression a == b, if a.__eq__(b) returns NotImplemented, then Python tries b.__eq__(a). If b knows enough to return True or False, then the expression can succeed. If it doesn't, then the runtime will fall back to the built-in behavior (which ...
Should a return statement be inside or outside a lock?
...ideal, but I wouldn't bend the code out of shape just to achieve it... And if the alternative is declaring a local variable (outside the lock), initializing it (inside the lock) and then returning it (outside the lock), then I'd say that a simple "return foo" inside the lock is a lot simpler.

The code block with the static modifier signifies a class initializer; without the static modifier the code block is an instance initializer.
Class initializers are executed in the order they are defined (top down, just like simple variable initializers) w...
