This is really interesting. Is there any hope for a hybrid language? Like python with haskells time system, or writing lambda functions like lisp and using python to execute? Basically, taking the 'best' parts of languages and combining them.

What about multiple definitions for functions depending on what kind of input is given. Like python has no tail recursion, but lisp does. Write a python function that gets transparently translated to lisp to utilize the features of the language.

This isn't related to a hybrid language per se. IPython runs a language core and then provides a notebook frontend atop it.

You could perhaps have multiple language cores each communicating problems to one another via the common language of the notebook... but that's nothing more than any other text serialization route with all of the challenges therein.
