Similar issue​: https://rt.perl.org/Public/Bug/Display.html?id=125247
(unclosed multiline comments). This time it is about other unclosed things.

Code​:
say $<word;
# some code here

Error​:
Unable to parse quote-words subscript; couldn't find right angle quote
at ./test.pl​:25
------> <BOL>⏏<EOL>
  expecting any of​:
  argument list
  term

Similar problem with​:
say <word;
say <<word;
say (word;
say [word;
... more?

1) "expecting any of" section does not help that much. There is no need to
add terms or argument lists to the end of your file to fix the problem, the
only thing that is actually expected is a closing bracket.
2) The end of file does not count as a helpful line number, especially if
the file is long. It would be great to have the same "(corresponding < was
at line 1)"-like message as with multiline comments

Unfortunately not all of the things are covered. For example​:

perl6 -e 'my $x = q​:to/foo/;
blah
'
===SORRY!=== Error while compiling -e
Ending delimiter foo not found
at -e​:3
------> <BOL>⏏<EOL>
    expecting any of​:
        whitespace

Then there's also​:
* https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6
/Grammar.nqp#L3741
* https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6/Grammar.nqp#L3780-L3792

And maybe other things too. For example, nqp itself prints a similar error message and does not mention the starter. I don't know if any user will ever see the error message from NQP though.

So there's a lot to be done to resolve this ticket fully…

Oh, also! I did not remove “expecting any of​:” part. This has to be done also.

Ah, sorry. Even though some tests are needed, this ticket is still not fully resolved. I'll try to split it right now.

OK. There are 5 new tickets for all other issues. In this particular ticket let's talk about (), [], "", etc. Basically, anything that currently says “corresponding starter” (word “starter” instead of the actual starter). It should really print the actual starter, but for now it's a good way to figure out which error message you're seeing.

Try to cover as many things as you can in tests and we'll close this ticket.

See rakudo/rakudo@6542bb8 for some info.
