NAME¶
Builtins::copy - Copy a value
SYNOPSIS¶
any copy( any x )
ARGUMENTS¶
x The value to copy
DESCRIPTION¶
Create a deep copy of any value. Contrasting with assignment, which creates
another reference, this function traverses the entire structure and creates a
clone. Note that this function is
not pure, as even called with the
same input, it returns a
different copy each time.

-
a = [5,6,7];
myFunction(a); // pass by shallow copy
myFunction(copy(a)); // pass by deep copy
Copying a structure containing a foreign pointer (for example a database or file
handle, or a piece of binary data) will copy the pointer but will
not
copy the contents of that pointer.
