For multiline return statements show more than the first line

Now only the first line in showed.

The division of line into 'pieces' in https://github.com/alexmojaki/stack_data will let you do this without having to add extra lines of context for single-line statements.

There's a point in leaving it be though: the standard traceback printouts have only the first line the same way.

I'll look for a way to implement it with this constraints:

• no files should be opened and read
• no surrounding code is shown (i.e. the function), only the expression/statement
• for cases with nested comprehensions and all only the innermost node is printed

I looked through the stack_data code and couldn't understand if there are the relevant functions or code bricks, so I'll repeat my reading. Do you think it is implementable?

no files should be opened and read

That's fine, that's what linecache is for.

no surrounding code is shown (i.e. the function), only the expression/statement

Pieces split lines up according to statements. You can get just the main piece by providing Options(before=0, after=0).

for cases with nested comprehensions and all only the innermost node is printed

stack_data doesn't provide that, but it's a bit of a weird goal. Can you show an example and explain why you want that?
