Hi, just curious.

When building a list, normally I do [a,b,c,d].

Is it possible to write a function to build a list [a]?

so that I can write [a,b,c,d] as "getBuilt $ build a b c d"?

looks like build will have to be of type ListBuilder, where ListBuilder a =
a -> ListBuilder a. Is it a fix point?
