survey

Survey Go-language source code and report usage statistics. Builds reports like this:

• Go 1.13 source code

• Russ Cox's Go Corpus

This is a concurrent Go program. Surveying the Go Corpus on my personal computer (after splitting per the comments in split.go) parses those 752 MiB of Go source at 450 MiB/sec. This is a testament to Go's efficiency.
