Problems with dynamic function creation.

[Steven W. Orr]

I have some functions I need to create at runtime. The way I'm creating 
them is by calling a function which returns the string representation. 
Then I exec the string.

Here's the code I use to gen the strings:
mkfactfns.py
-----------
import new
def mkfactfns( cname ):
     def auxgen( name, params, dd ):
         v1 = ( """def mk%s%sdict(%s):\n"""%(name, cname, params)
                +
                """    print 'In mk%s%sdict'\n"""%(name, cname)
                +
                """    return %s\n"""%dd)
         v2 = ( """def mk%s%s(%s):\n"""%(name,cname,params)
                +
                """    print 'Calling mk%s%s'\n"""%(name,cname)
                +
                """    return %s%s( mk%s%sdict(%s) )\n"""%(name,cname, 
name, cname, params))
         return v1, v2
     return auxgen

This is  the caller of mkfactfns
--------------------------------
import mkfactfns
fbase = "ABC"   # Factory BASEname
auxfactgen = mkfactfns.mkfactfns(fbase)

Then in the same module, I call auxfactgen
via
     mkfactfns.AuxFnDefs( auxfndata, auxfactgen, globals(), "ABC" )

def AuxFnDefs(auxfndata, fnmaker, globs, cname ):
     dictsuff = ('dict','')
     for ii in auxfndata:
         rr = fnmaker( *ii )
         for jj in range( 2 ):
             co = compile (rr[jj], '', 'exec')
             exec co
             name = 'mk%s%s%s'%(ii[0],cname,dictsuff[jj])
             print 'co = ', co, 'name = ', name
             nfunc = new.function( co, globs, name )
             print 'Just added mk%s%s%s'%(ii[0],cname,dictsuff[jj])
             globs['mk%s%s%s'%(ii[0],cname,dictsuff[jj])] = nfunc
             print 'g = ', globs['mk%s%s%s'%(ii[0],cname,dictsuff[jj])]

Everything works just fine (that I know of) except that when I run a 
function that takes 1 arg, I get the following message:

TypeError: ?() takes no arguments (1 given)

even though I know that I am passing one arg. I must be doing something 
wrong, I just don't know what. :-(
