Indeed!
Go has while loops :)
for {
// do some stuff
if !condition { break }
}
instead of
{
// do some stuff
} while condition
They are identical functionally, so why bother with the second syntax? You
then get into arguments about which one to use.

Languages often have a whole variety of loop constructs.
C has for loops as well us while loops.
Go adopts the principle from the Zen of python:
*There should be one-- and preferably only one --obvious way to do it. *It
takes a minimalist approach - there is only one looping construct: the for

I don't miss MUMPS post conditional either.

Thanks, Dan. Those seem like well-reasoned points.

There are two parts. The worse part is the negative conditional
(unless), which has the problem that humans are bad at negations;
nearly always when there is a complex condition with an "unless", it
needs to be mentally refactored into an "if !" (when working through
other people's bugs, I
I don't think I'm personally sold on this proposal either, but I'm curious
what bad experiences you've had with post-fix conditionals. I haven't
personally used a language with post-fix conditionals and it sounds like
that might be to my benefit :)

My first professional programming language was Perl, decades later I
still wake up in a sweat thinking about post-fix conditionals and the
'unless' conditional.
Please no.

Hello Gophers,
There's two tiny pieces of syntactic sugar I really miss from a few other
languages that I think would add a nice bit of ergonomics and convenience to Go
(which I now play as my main) without increasing any magic or spooky action at
a distance.
They are:
- postfix conditionals
