Re: Empty function determination

["Grisha" <grisha@...>]

The simple solution is to create some global empty function, and if you want
to pass empty function - pass this global.

function globalEmptyFunction()
end

function MyFunc(f)
    if f == globalEmptyFunction then ...
    else ...
end

Other than this, the only way I can think of is to use lua internals to
check that there are no instructions in the function, and I don't think it's
a nice thing to do.

Grisha
