复合词的文件名约定？

Question

Is there a common convention in Go to name files that contain compound words?

For example I wrote an implementation of the Weighted Union Find algorithm and put it into its own source file. How should I name the file?

// mixed case
weightedUnionFind.go

// lower case
weightedunionfind.go

// snake case
weighted_union_find.go

I found only a convention regarding package names and the following question about file naming conventions in general, What are conventions for filenames in Go?.

Therefore I grepped through Go package source files and ended up with weightedunionfind.go.

Although it's not formally specified in https://golang.org/doc/code.html#Overview - snake_case is the convention across the most of the standard library and most third party libraries.
