""" | |
Interactive execution with automatic history, tries to mimic Mathematica's | |
prompt system. This environment's main features are: | |
- Numbered prompts (In/Out) similar to Mathematica. Only actions that produce | |
output (NOT assingments, for example) affect the counter and cache. | |
- The following GLOBAL variables always exist (so don't overwrite them!): | |
_p: stores previous result which generated printable output. |
