changing local namespace of a function

Maybe it is just my laziness. It is almost intolerable for me to write 
lines and lines of code like

   d['z'] = func(d['x']+d['y']+d['whatever']['as']+d[a][0] )

It is ugly, unreadable and error prone. If I have to use this code, I 
would write

   _z = func(_x + _y + _whatever['as'] + _a[0])

and use a perl script to generate the real code. (See, I am not lazy :-)
