Hello all,
I have been looking in perldoc and perlfaq trying to find more info about typeglobs. I am just trying to see if the code below is an appropriate use and not an abuse of a typeglob ( I really want it to be okay) but don't want to use it if there are good reasons not to.

Obviously the example is simplistic, I would use it in roughly the same manner in the real code. It does work the way I expect and want it to work, i am just not familiar enough with perl to know what is really going on behind the scenes. Anyway here is the code: 

#!/usr/bin/perl -w

use strict;

open FH, '/tmp/configfile' or die "Could not open file: $!\n";
my $foo=<FH>;
close FH;

my @foo=split(//, $foo);
my $foo1=join("",@foo[0..2]);
my $foo2=join("",@foo[3..5]);
my $foo3=join("",@foo[6..16]);
my $foo4=join("",@foo[17..19]);
my $foo5=join("",@foo[20..24]);


foo1(*$);
foo2(*$);
foo3(*$);
foo4(*$);
foo5(*$);

sub foo1{
    print "$foo1\n";
}

sub foo2{
    print "$foo2\n";
}

sub foo3{
    print "$foo3\n";
}

sub foo4{
    print "$foo4\n";
}

sub foo5{
    print "$foo5\n";
}

Here is the contents of /tmp/configfile:

123 abc abc@123.com lp2 12345

Here is the output of the script:
123
abc
abc@123.com
lp2
12345

Thanks in advance - Aseidas
