Expand description
A single token or a delimited sequence of token trees (e.g., [1, (), ..]).
A token stream surrounded by bracket delimiters.
A single punctuation character (+, ,, $, etc.).
A literal character ('a'), string ("hello"), number (2.3), etc.
Returns the span of this tree, delegating to the span method of
the contained token or a delimited stream.
Configures the span for only this token.
Note that if this token is a Group then this method will not configure
the span of each of the internal tokens, this will simply delegate to
the set_span method of each variant.

Prints the token tree as a string that is supposed to be losslessly convertible back
into the same token tree (modulo spans), except for possibly TokenTree::Groups
with Delimiter::None delimiters and negative numeric literals.
