Or, the language designer thinking he's saving programmers work by jus returning the value in cases where there is a list of length one.
However, he's really making it worse because now all return values from that function have to be type-checked to see whether they are scalars or lists.
R comes to mind, where once in a blue moon a matrix result will happen to only have a single column, which R helpfully decides should be turned into a simple vector, which then doesn't have the matrix operations available anymore (like dim()), and kaboom!
Yeah. I learned LISP pretty early in my career, wrote a few LISP interpreters, and those are indeed the kinds of bugs that I was stomping. PowerShell seems to have turned those bugs into language features. Augh.
