At least problems can be easily circumvented.

I know and that's something I'm probably going to be wondering about for
all eternity -.-

I'm not a fan of adding new keywords for something like this...

>   foo()
> afterwards [do]  // or even "then" would make sense (from english reading
perspective)
>   bar();

That "then" is a great idea! That would definitely not break anything and
it would make sense indeed:

=== code begin ===

while bool do
  foo
then
  bar;

repeat
  foo;
until bool then
  bar;

=== code end ===
