This project tries to find a way to determine if a string is a const, in an efficient way.
The simple idea is to create a long string which is a concatenation of all strings. Then we create the individual strings from it.
In practice we would want to use go generate to create the separate strings, very similar to stringer.
See this blog post by Rob Pike for details on go generate and stringer: https://blog.golang.org/generate
Then to determine if a string is a const, we check if the memory for the string is inside a larger string. We expect that can be done in a few machine instructions.
