If you accidentally put "use" twice with a module that has double colons in the name, the error is LTA as says nothing of the actual reason for failure and also lacks any references such as file names or lines.

<Zoffix> m​: use use Foo​::Bar
<camelia> rakudo-moar 15ee3c​: OUTPUT«===SORRY!===␤Could not find symbol '&Bar'␤»

It happens regardless of whether the actual module exists or not​:

$ tree
.
└── Foo
  └── Bar
  └── Ber.pm6

2 directories, 1 file

$ cat Foo/Bar/Ber.pm6
unit class Foo​::Bar​::Ber;

$ perl6 -I. -e 'use use Foo​::Bar​::Ber'
===SORRY!===
Could not find symbol '&Ber'

Running this with RAKUDO_MODULE_DEBUG=1 shows that it doesn’t even try to load it as a pragma first​:

$ RAKUDO_MODULE_DEBUG=1 6 'use use Foo​::Bar'
  90921 RMD​: Loading settings CORE
  90921 RMD​: Setting up default paths​: . blib
  90921 RMD​: going to load Perl6​::BOOTSTRAP
  90921 RMD​: Settings CORE loaded
===SORRY!===
Could not find symbol '&Bar’

Compare with​:

$ RAKUDO_MODULE_DEBUG=1 6 'use Foo​::Bar'
  90923 RMD​: Loading settings CORE
  90923 RMD​: Setting up default paths​: . blib
  90923 RMD​: going to load Perl6​::BOOTSTRAP
  90923 RMD​: Settings CORE loaded
  30 90923 RMD​: Attempting 'Foo​::Bar' as a pragma
  6 90923 RMD​: 'Foo​::Bar' is not a valid pragma
  1 90923 RMD​: Attempting to load 'Foo​::Bar'
  0 90923 RMD​: Late loading 'Foo​::Bar'
