I like it, not because it outputs HTML, but because it presents lists
nicely.
I like Reinteract because it is great for experimenting things. So,
what if, when receiving a list of CustomResult objects, they would all
be drawn as a list. With list comprehensions, such list would be great
for experimenting with different parameter values, like:
[ plot( f(x, 5) ) for x in range(-5, 5) ]
[ rere.search(x, 'foo') for x in ['foo', 'foo|bar', '[a-z]+'] ]
That way you would immediately see which values suit best in whatever
case you are doing.
Better yet, drawing nested lists of CustomResults as two-dimensional
tables... Although that would eat a lot of screen space.
