<masak> but I find it fairly easy to forget to remove a trailing comma
before the block.

With current Rakudo​:

$ ./perl6

for 1,2,3, { say $_ }
Missing block at line 2, near ""

This is Rakudo Perl 6, version 2010.07-113-gc41bcd7 built on parrot
2.6.0 r48341

The RT System itself - Status changed from 'new' to 'open'

From @bbkr

When namespace is not defined in CATCH block it gives misleading message about missing block.

$ perl6 -e 'CATCH {when X​::Y {}}'
===SORRY!===
Missing block
at -e​:1

Tested on Rakudo star 2012.07

FWIW this is not related to CATCH at all. Since X​::Y is parsed as a
listop, the block is parsed as as an argument to the listop, and then
'when' misses its block. And yes, we should have a better error message
for that.

As of latest Rakudo​:

  $ perl6 -e 'for 1,2,3, { say $_ }'
  ===SORRY!===
  Expression needs parens to avoid taking the block
  at -e​:1
  ------> for 1,2,3, { say $_ }â��<EOL>
  Missing block (apparently taken by expression)
  at -e​:1
  ------> for 1,2,3, { say $_ }â��<EOL>

  $ perl6 -e 'CATCH { when X​::Y {} }'
  ===SORRY!===
  Function 'X​::Y' needs parens to avoid taking the block

  Missing block (apparently taken by 'X​::Y')

Can be closed now, unless tests are somehow needed.

Yes, should be tested; can be done hopefully with typed exception test. Tagging testneeded.

test. Tagging testneeded.

Added a typed exception in rakduo PR #​260, added tests for the two cases mentioned in this ticket in roast commit d6b8fac.
