(Request) Else-if chains

[developedby]

Long chains of if-else-if-else-if-else are annoying to right now as they will continuously increase
indentation.

I propose a python-like if-elif-else

if a:
  ...
elif b:
  ...
else:
  ...

Other options for keywords are elsif and else if

An alternative syntax would be like a switch

if:
  case a:
    ...
  case b:
    ...
  else:
    ...

Or using when like in bend.
I like the first one because it is already what people expect from a python-looking language.
