Fair enough, but in TimToady's original, he had 'CASE'.($var+0) which avoids dieing. 

P:\test>perl -le" print 1; $var = 'foo'; goto 'CASE'.($var+0); CASE0: 
+print 2;"

And that allows CASE0: to become the default.

The only situation this doesn't cover is when $var is undef'd; but then none of the other solutions handle that (except the do{ local $^W; $var + 0 }; I suggested).
