In elisp, there is an 'if' case where I would like to perform many different things: (if condition (do-something) (do-something-else) ...) However, (do-something-else) is executed in the else-case only. How can you specify a block of instructions to execute? For example: (if condition (begin (do-something) ...

Hi there. I have a rather unusual use case whereby I need to be able to obtain the number of parameters a given block has been defined to take. For example... foobar(1,2,3) { |a, b, c| } def foobar(x, y, z, &block) # need to obtain number of arguments in block # which would be 3 in this example end From what I understand, this is...
Is it possible to define an instance method in ruby from a string (the method name) and a block (the method's contents)? I imagine this will need to use instance_eval(), but I haven't figured out how to mix the two data types yet.
