cannot find Voice

[Erik Sandberg]

Hi,

The following code produces five warnings
warning: cannot find Voice: A

but the paper output is perfect.

\version "2.1.34"
\score {<<
  \new Staff \notes { a4 a a a \context Voice=A {a a a a}}

  \lyricsto A \new Lyrics \lyrics { a a a a }
>>}

The following code gives the same output without warnings. IMHO, both ways 
should be allowed:
  \new Staff \notes \context Voice = A { \new Voice {a4 a a a} a a a a}
