Re^4: The Concept of References

One could argue that a pointer in C, e.g. to a struct tm, knows what it points to

In C the programmer tells the pointer what it points to. In Perl the reference knows what it points to. It's an important if subtle difference.

Eh, not quite. The reference doesn't know. The difference is that in Perl, the thing the references points to, knows what it is. In Perl, SVs are typed.	[reply]
