Expand description
This module contains free-standing functions for creating AST fragments out of smaller pieces.
Note that all functions here intended to be stupid constructors, which just
assemble a finish node from immediate children. If you want to do something
smarter than that, it belongs to the ext submodule.
Keep in mind that from_text functions should be kept private. The public
API should require to assemble every node piecewise. The trick of
parse(format!()) we use internally is an implementation detail – long
term, it will be replaced with direct tree manipulation.

- While the parent module defines basic atomic “constructors”, the
extmodule defines shortcuts for common things. - tokens
