Class parsing consumes newline if class is just one line

[JSAbrahams]

Description of Bug

When parsing a class, when it is a single line, the newline at the end of the line is consumed by the parse class function. This causes the file parses to throw an exception because it expects a newline at the end of the line. The exception is thrown at the location of the next token.

Expected behavior

The class parses should not consume any newline token.

Probable fix

This is one situation where we need to peek multiple tokens ahead.

• If there is one (or more) newline, followed by an indent, then this class is followed by a block. This block must be parsed and is the class body.
• If there is one (or more) newline, followed by any other token, then what comes after this class is irrelevant for this parse function and we exit.

[JSAbrahams]

It should actually be possible to precede a block with an arbitrary amount of newlines. This functionality has been implemented in the case of classes, and when parsing blocks themselves. However, all other places which take blocks should peek ahead to see if there is (a string of) newlines before parsing a block. Should check, off the top of my head:

• if else
• while
• for
• with
• function definition
