Oh fellow monks, please enlighten me, for this has me stumped: 
@a=('a', 'b', 'c');

test1: 3
Use of uninitialized value at t2.pl line 3.

This is, when scalar is applied to the value returned by sort it returns undef. Does sort return something different in a scalar context? But then scalar should not be setting a scalar context, since its purpose is to get an array as argument.

What am I missing?

Thanks,
