    "DrScheme provides and enforces this batch-oriented style of
interactive program
evaluation in a natural way. When the programmer is ready to test a program,
a click on the Execute button submits the program to the interactions window.
When the programmer clicks on Execute, the repl is set to its initial
state and the
text from the definitions window is evaluated in the fresh
environment. Thus, the
repl namespace exactly reflects the program in the definitions window. Next, the
programmer evaluates test expressions in the repl [...]"
