However, perl does provide the pack and unpack functions for squeezing 
variables into machine-dependent quanta. This is very useful when a 
precise data structure must be provided, such as when using library 
functions or a message-passing interface.

Win32::API::Structure also provides the ability to use C structures.

Sorry, perl has no concept of variable type.  Any variable is beaten into
the form necessary for the context in which it was called.

$bob = "abc"
print $bob + 5;

"5"
