Why I Like Perl

Loose Typing System

don't have to specify what variables can hold
DWIM
- if you use it like a string, it's a string
```
  $a = 123;
  $b = 'abc';
  print $a . $b;
```
if you use it like a number, it's a number
```
  $a = 'a';
  $a++;
  print $a;
```
type system cares more about scalars and lists and hashes anyway
