trait Names extends AnyRef
EXPERIMENTAL
A slice of the Scala macros context that provides functions that generate fresh names.
In the current implementation, fresh names are more or less unique in the sense that
within the same compilation run they are guaranteed not to clash with:
1) Results of past and future invocations of functions of freshName family
2) User-defined or macro-generated names that don't contain dollar symbols
3) Macro-generated names that are created by concatenating names from the first, second and third categories
Uniqueness of fresh names across compilation runs is not guaranteed, but that's something that we would like to improve upon in future releases. See https://github.com/scala/bug/issues/6879 for more information.
