rakudo commit 67a75c1e1d9ed99326b7e426eea3cd969dba35ea
Date:   Sat Feb 28 16:16:52 2015 +0100

Accidentally called $class.new(...) without a matching signature. The 
compiler correctly reports that it could not find a matching signature, 
but incorrectly does *not* report the package/file/line where the bad 
call occurred. Incidentally, the signature it *did* try has a trailing 
'*%_' that doesn't occur in the actual code, but that may be a compiler 
artifact.

The entirety of the error is:

--cut here--
===SORRY!===
Cannot call 'new'; none of these signatures match:
:(Polar $: Real \mag, Real \theta, *%_)
--cut here--

Below is the class, followed by the admittedly incorrect attempt to 
invoke it:

--cut here--
class Polar {
     proto method new(|) { * }
     multi method new(Real \mag, Real \theta) { }
}

constant j = Polar.new( 0e0 );

say j.re;
--cut here--
