Code:
repeat { } while;
OR
repeat { } until;

Result:
Whitespace required after keyword 'repeat { } until'
at ./test.pl:2
------> repeat { } until⏏;
Missing "while" or "until"
at ./test.pl:2
------> repeat { } until⏏;
    expecting any of:
        prefix
        term

It is similar to #125596, but less brutal.
If you put a whitespace (it is asking for it!) then it will print the last
part of the error – Missing "while" or "until". Then what? repeat { } until
until;? :)
