hen to access a
lexical by name involves a sequential search through the (probably not
large) array of names, to get the index, then the index is used to get
the lexical from the other array.
Or would that make access by name too slow?

I am sure they will be a PMC. In fact two different patches have been

Sean's has not been committed yet, probably because he is waiting for a

Sounds like we want objects *and* classes to support:
static_attribs - which are defined at compile time and
accessed by offset probably stored in an array.
dynamic_attribs - which come and go at run time and are
generally accessed by name and likely stored in a hash.

Why is there a callmeth op? Can't we just use a regular invoke as with other

Also, should the current 'invoke' op be changed to 'call'? I don't care
exactly what the names are, but consistency is nice.

This seems like a nice approach to me as it simplifies the Parrot_Context
struct and the calling and returning from subs and methods.
Comments?

to comment on my idea for getting rid of
the register stacks etc:
"calling convention and continuation ramblings"

tacks
c. opcode, stacks and half of the registers
d. opcode, stacks and all of the registers
The patch I sent supports two types: type b (in continuation.pmc) and type d
(in completecontext.pmc). Also in this patch is the option to not create a
new continuation --as in a tail call-- which of course makes it very fast.

verything. If a sub uses only one or two
registers it only needs to save those before calling another sub ... right?
