Indeed. I was initially not completely correct, and should have said:
the 'const' modifier prevents creation of the local copy of the argument.
The exact way of creating local copy depends on the argument type: for reference-counted types, it
is done by manipulating the refcount, other types like shortstrings use a plain copy, etc.
