I pitched a book called Perl for Python Programmers[0] and it included an
entire chapter about how important context is when understanding Perl.
So there's the *number* contexts: void, scalar, list
And there's the *type* contexts: number, string, references
there is also integer context provided by indexing and various builtins
that have index or length args (substr, splice, etc). this is why you
can do the great pick a random element from an array like this:
my $rand_val = $array[rand @array] ;
no need for an int() there as indexing is an integer context.
there is also boolean context.
the Want.pm module has access to even more contexts like ASSIGN and
howmany().
thanx,
