Go中5个秘密关键字是什么？

In this talk, Francesc Campoy has a slide with Go's 25 keywords, and apparently 5 'secret' keywords.

What are the 5 secret keywords in Go?

The following 5 keywords are ignored:

notwithstanding
thetruthofthematter
despiteallobjections
whereas
insofaras

Yes, really.

Update: As Deleplace notes in the comments, the easter egg keywords have been removed. It looks like this commit took them out during a major parser update. If you try to run a program containing one of these tokens, you'll find they're treated as ordinary identifiers now.

There are some easter egg keywords in the lexer (lex.go) that are not in the official documentation, and hence are ignored by the compiler.

Here they are:

notwithstanding
thetruthofthematter
despiteallobjections
whereas
insofaras

You can report to this conversation for more details.

It looks like the secret keywords will be removed in v1.10. See here.

For anyone curious, here is the commit which introduced the keywords.
