NightShade Vs. Euphoria++

Hmmm..
Before I can start coding on U4IA++ again, I should
know what syntax to use...
Euphoria's, or Gothic NightShade's?

If I'd opt for NightShade, the package will be 'Gothic
NightShade' and not U4IA++.
NightShade being a totally new language closely
releated to Euphoria (read: it *is* Euphoria, just
with other datatypes).

So I'll need *you* to tell me wich one to go for.
Remember, I can get a NightShade To C and C To
NightShade translator out there even before the Beta-1
release of RDS' E2C.

You will have to choose now.
To let you pick, below are two graphics programs, one
written in Gothic NightShade, and one written in
U4IA++.
Both come with the benchmark results after being
translated to C.

---------------U4IA++ program-------------------------
include image.e
include graphics.e

sequence bmp
bmp = read_bitmap("test.bmp")

if graphics_mode(get_mode(640,480,16)) = -1 then end
if

atom t, cnt
cnt = 0
t = time()
while t+10 > time() do
   display_image({0,0},bmp[2])
   cnt+=1
end while
printf(1,"%d blits per second",cnt/5)

if wait_key() then end if

-------------Gothic NightShade Program----------------
include image.e
include graphics.e

integer array bmp
bmp = read_bitmap("test.bmp")

if graphics_mode(get_mode(640,480,16)) = -1 then end
if

atom t, cnt
cnt = 0
t = time()
while t+10 > time() do
   display_image({0,0},bmp[2])
   cnt+=1
end while
printf(1,"%d blits per second",cnt/5)

if wait_key() then end if

U4IA++ Version: 218 Blits Per Second
NightShade Version: 312 Blits Per Second


I gave this example bvecause it illustrates the speed
of NightShade datatypes over Euphoria datatypes.
The only difference between U4IA++ and NightShade are
the datatypes.
These are:
integer
atom
object
string

Ofwich each can be decalerd as follows:
integer a
a = 10
integer array as
as = {10,50,60,{20,30,40},40}

atom f
f = 3.14
atom array f
f = {2.5,3.14,{1.0,2.3}}

object o
o = "YOU SUCK!"
o = {3.14,3.14*2}
object array os
os = {"YOU SUCK!!!",3.14,2}

string s
s = "MTS RULES!"
string array ss
ss = {"MTS RULES!","RDS SUCKS!"}

That's it!
For the rest, the syntax and library routines are
exactly the same as U4IA++.
This means that you have OOP support in the form;

type myclass()
integer age
string name
procedure doshit()
   puts(1,sprintf("%s is %d!!",{name,age})
end procedure
end type

myclass test
test.age = 17
test.name = "MTS"
test.doshit()


The only thing NightShade doesn't handle very
effectivly (due to speed issues) is object arrays.
Each object is fairly large and complex.
Therefore you shouldn't use arrays of objects too much
if you'd like to hang onto memory.

I, or any lamer with half a brain, can code a Euphoria
To Gothic NightShade translator. All that has to be
changed is 
'sequence' into 'object array'.


Wich language do you find the best?
