## Changes from version version 2020 12 02 to version 2020 12 07

This release fixes an error that was discovered in the behavior of the -wn flag in version 2020 12 01:

    - Fixed issue git #47, incorrect welding of anonymous subs. 
      An incorrect weld format was being made when the --weld-nested-containers option
      (-wn) was used in to format a function which returns a list of anonymous subs.
      For example, the following snippet was incorrectly being welded.

    $promises[$i]->then(
        sub { $all->resolve(@_); () },
        sub {
            $results->[$i] = [@_];
            $all->reject(@$results) if --$remaining <= 0;
            return ();
        }
    );

    This was due to an error introduced in v20201201 related to parsing sub
    signatures.  Reformatting with the current version will fix the problem.
