grep can take a BLOCK with multiple tests and/or you can just use and and chain multiple checks (recommended best practice is to use the BLOCK form rather than the EXPR form these days anyhoo). Or use something like File::Find::Rule rather than lower level primitives. 

my @F = grep { /^\w/ and not -d "$myDir/$_" } readdir( I );

Edit: Path::Tiny is another possibility.

use Path::Tiny;
my @files = grep !$_->is_dir, path( $myDir )->children( qr/^\w/ );
