       Operations on internal representations of values.

       Not for the casual user.

       Computes  the  total  size  (in  words,  including  the  headers)  of all heap blocks accessible from the
       argument.  Statically allocated blocks are included.

       Since 4.04

       valfield : t->int->tvalset_field : t->int->t->unit

       When using flambda:

       set_field MUST NOT be called on immutable blocks.  (Blocks allocated in C stubs, or with new_block below,
       are always considered mutable.)

       The same goes for set_double_field .

       For experts only: set_field et al can be made safe by first wrapping the block in  Sys.opaque_identity  ,
       so any information about its contents will not be propagated.
