Arguments are usually done with 
sub f {
   my ($arg1, $arg2) = @_;
   ...
}

or 

sub f {
   my $arg1 = shift;
   my $arg2 = shift;
   ...
}

Using $_[0] is rarer.

Also, C style for loops are generally ugly and unperlish

True, but none of your alternatives are particularly better. I would move the my into the loop, though. 

for (my $i=1; $i<=100; $i+=2) {    # 1, 3, 5, ..., 99
