Just to focus on the differences between lambdas and Procs, a lambda acts more like a real method. What does that mean?
Apparently it means a lambda is less ($@(#$ insane.
-
When you create your own function to accept procs, the guts need to change a little bit because you'll need to use #call instead of yield inside (because which proc would yield run if you had more than one?).
Too much special!! Why the special cases? Just so that one can type
yieldinstead of invoking a function and naming the argument? -
Use that block of code (now called a Proc) as an input to a function by prepending it with an apersand &
Oh, Ruby. This is entirely too confusing. Why is the ampersand required to signify that something is passed as a block, especially given that it has a type (
Proc)? What does it mean if the ampersand isn't used?
