Make it a habit to study the docs for the functions you are
using:
perldoc -f grep
perldoc -f readdir
oddly- the grep documentation in perldoc doesn't even mention
filehandles. readdir does show proper use though- when i looked up
grep in the perldocs, the issue remained unclear to me.
The grep() documentation doesn't mention filehandles because the
purpose of grep() is to deal with a LIST, irrespective of how the LIST
was generated. A filehandle within <> symbols may return a list in
list context. An array may as well, as does the plain
('one', 'two', 'three') notation or any function or operator that
returns a list...
