Because packing values into interface{} causes allocations
this gives us a major improvement on allocation count, but
tag is bigger so a significant loss on bytes allocated.
It is a minor performance win overall, especially in the
null exporter case when it really matters the most.

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
Report Issues / Send Patches
This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your subdir):" in the subject line, so it is easy to find.
