Support for inline eval
some haskell editor like leksah support for inline eval which is very convenient for documentation and testing, demos, debugging...
I envision two ways to use it: Interactively, in a comment line, if the user select the text to be evaluated and select eval in the menu, haskero would append "= [result]" after the expression.
if the comments have some special scape sequence, like for example @[expression]==@ the program can insert the values returned after each recompilation.
