Comment (by tscrim):
The issue is that when calling preparse, if the first line is a comment
(IDK why it would start with a `!`...) then it does not preparse anything
further. Specifically, if there is a multiline statement that you want to
preparse, but the first line is a comment, it doesn't do anything. For
example:
{{{
# Comment
def foo(x):
R.<y> = QQ[]
return x * y
}}}
would not get preparsed. Given the description, the preparser works on the
assumption that the input is a specific self-contained line, but it seems
to have the functionality to handle multi-line input. I think we should
either see if there is a line break and then preparse the rest after the
comment line or very explicitly state the assumption.
