Perl Best Practices also mentions an edge case where the ampersand is
treated as a bitwise-OR operator:
=begin perlbp page=176
On the other hand, the ampersand itself is visually ambiguous; it can
also signify a
bitwise AND operator, depending on context. And context can be extremely subtle:
$curr_pos = tell &get_mask( ); # means: tell(get_mask( ))
$curr_time = time &get_mask( ); # means: time() & get_mask( )
=end perlbp
