Re: [Caml-list] Deep copy

[Ken Wakita <wakita@is.titech.ac.jp>]

I apology that I sent a silly code fragment last night.  I included two
mistakes.

Small one: the order of arguments to to_string was wrong.  it should be:

    Marshal.from_string (Marshal.to_string obj [Marshal.Closures]) 0

Worse one: it does not work for OO features (sigh).

Sorry for disturbance.

Ken
