Yes, I have an alternative solution:
The risk is minimal, that you would misspell the context name to a voice name 
that already exists somewhere. So I would say that if you have written
\lyricsto foo blah
then you should get a warning if there is no note in the current context(?) 
which belongs to a voice called foo.

So this would give a warning
<<
\context Voice=foo { c c c c } 
\lyricsto Foo blah
>>

but this wouldn't:
<<
\context Voice=foo { c c \context Voice=bar c c } 
\lyricsto bar blah
>>

In the second example, there _are_ notes to couple "blah" with, so there was 
most likely no misspelling.


I suppose that you could generalise the rule to the following: A warning 
should be issued once for each lyricsto, if lilypond fails to couple each 
syllable to a note. (this would also cover the quite common problem where an 
error makes you end up having more syllables than notes)

Does this sound sensible?

ps. A secondary question is this: How should lilypond interpret the following 
code? Should 'blah' be coupled with the c:s or the d:s, or both?

\new Staff \context Voice=foo { c c c c } 
\new Staff \context Voice=foo { d d d d } 
\lyricsto foo blah
