desc="Aliasing Values">
These alias templates allow giving a new name to existing values.
They are most useful for avoiding too many template-generated variables.
If an alias name matches the name of the source,
then no alias will be generated;
this behavior is useful when generating aliases in templates where the
caller may or may not choose a name that would otherwise conflict with
its internal representation.
If no description is provided,
aliases will inherit the description from the source symbol.
