Perhaps you can't do lambda foo: print foo, but you *can* do lambda x:
sys.stdout.write(x).

Combined with the ternary if, it seem sufficient if you want to stick
to the ideal "Simple is better than Complex". Sure, with statements
allowed in anonymous functions, you can save on a line of typing (def
blargh(x):), but I don't feel the obfuscation is worth the cost.
