I'm in the process of learning Scala and I came across a scenario today where I need to map multiple functions over a single piece of data and wondered if there was a formal name for this. It sort of feels like the inverse of map.

I'm not sure this is the correct way of expressing it, but this is what I did:

dmap(x: Object, fns: List[Function]) = fns.map(_(x))

Is there a built in way to do something similar? Is there a formal name for this function?

When would you NOT want to use functional programming? What is it not so good at? I am more looking for disadvantages of the paradigm as a whole, not things like "not widely used", or "no good debugger available". Those answers may be correct as of now, but they deal with FP being a new concept (an… >>> More

It seems to me that functional programming is a great thing. It eliminates state and makes it much easier to automatically make code run in parallel. Many programmers who were first taught imperative programming styles find it very difficult to learn functional programming, because it is so different… >>> More

I have always been skeptical of rewriting working code - porting code is no exception to this.
