intlist vs array

[Leopold Toetsch]

I did "cp t/pmc/intlist.t t/pmc/intlista.t" and
s/\.IntList/\.PerlArray/g in the latter.

After implementing the missing pop-methods[1] in array.pmc I ran both:

$ time parrot t/pmc/intlist_2.pbc
I need a shower.

real 0m0.097s
user 0m0.090s
sys 0m0.000s

$ time parrot t/pmc/intlista_2.pbc
I need a shower.

real 0m3.964s
user 0m1.540s
sys 0m2.410s

Raw timings in gprof's output are 0.05s / 0.63s.
PerlArray is spendig almost all the time in mem_allocate.

I vote for using intlist as the PerlArray base class.

The question arises: should we copy intlist* and make a general class
out of it storing a PMC or a typed UnionVal (like PerlHash), or would a
size parameter in creation time of the intlist plus some multiplications
be acceptable in intlist?
