Would you be allowed to switch contexts within a control structure?
class foo:
%sagex #this is useful
def bar(self,n):
return n*n
%sage
def baz(self,m):
n = float(m^3) #that's an exponent
%sagex #getting ugly...
cdef double p
p = n**(-2)
n = p - n
%python #holy crap
k = int(n*100000)
k = k ^ int(m) #that's an xor
return p*k
I kinda like how pyrex does it. Maybe you could _judiciously_ add a few new
defs.
xdef -> sagex
fdef -> f2py
wdef -> weave
...
I think the coolest thing about sage is that it's native language is python. I
personally believe that any programmer worth h(er|is) salt should be able to
rapidly switch between 3 to 10 languages at a time. However, that's a poor
philosophy when one wants to attract student programmers, or worse, SAGE users
(mathematicians, many of whom don't trust computers already).
