Speaking of dislike,

I have been using Powershell a bit more often the last few years. What I
still can not believe is the behaviour with returning a list from a

I the list has only one object in it it returns the object rather than the
list containing one object.

This is identical for functions you write or built in language functions.

Which makes it ridiculous if you are trying to assume the return from a
function is of type list (empty list or non empty list) as if it has one
member it becomes a object of a different type (not a list)

Not a fan of this decision at all.

you were my modulation, so that's what you will always be
we took each other higher, we set each other free
course, neither of us were wearing helmets, and our blood was just everywhere
and when the morphine kicked in later
the censors threw their hands up in despair
