This is a follow-up on https://golang.org/cl/161199 which introduced the new Go 2 number literals to text/scanner. That change introduced a bug by allowing decimal and hexadecimal floats to be consumed even if the scanner was not configured to accept floats. This CL changes the code to not consume a radix dot '.' or exponent unless the scanner is configured to accept floats. This CL also introduces a new mode "AllowNumberbars" which controls whether underbars '_' are permitted as digit separators in numbers or not. There is a possibility that we may need to refine text/scanner further (e.g., the Float mode now includes hexadecimal floats which it didn't recognize before). We're very early in the cycle, so let's see how it goes. RELNOTE=yes Updates #12711. Updates #19308. Updates #28493. Updates #29008. Fixes #30320.

Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).
Each file is a list of API features, one per line.
go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.
except.txt lists features that may disappear without breaking true
compatibility.
next.txt is the only file intended to be mutated. It's a list of
features that may be added to the next version. It only affects
warning output from the go api tool.
