Overview
The new() built-in function takes a type as argument, allocates memory of the given type and returns a pointer to it.
var ptr *some_type ptr = new(some_type)
We don't have to worry about de-allocating memory allocated with new(). It is automatically garbage collected.
new() and New()
The "errors" package exposes a New() function. Do not mistake it for new().
