to will not be mutated within the function.
* Don't let variable names shadow outer variables - use gcc's -Wshadow
option.
* Use the strictest possible data type where practical. For example
for an enumeration, use the actual enum type rather than just a
``gint``, use a ``gchar`` for individual (ASCII/UTF-8) string
characters rather than ``gint``, and use a ``guint`` for integers
which cannot be negative rather than ``gint``.
* Do not use G_LIKELY or G_UNLIKELY (except in critical loops). These
add noise to the code with little real benefit.
