What is the exact problem with multiple inheritance?
... 12 ... "speak" ... 4 byte function pointer
class B:
at offset 0 ... "foo" ... 2 byte short field
at offset 2 ... 2 bytes of alignment padding

subtle differences between JavaScript and Lua [closed]
...the for loop creates new local variables for each loop variable.
local i='foo'
for i=1,10 do
-- "i" here is not the local "i" declared above
...
end
print(i) -- prints 'foo'
The above code is equivalent to:
local i='foo'
do
local _i=1
while _i<10 do
local i=_i

__attribute__((weak))
void foo(void);
inline void foo(void) { ... }

Is there a way to access method arguments in Ruby?
...e name of the parameter and whether it is required.
e.g.
If you do

end
then
method(:foo).parameters # => [[:req, :x], [:req, :y]]
You can use the special variable __method__ to get the name of the current method. So within a method the names of its parameters can be obtaine...
Why can't we have static method in a (non-static) inner class?
