I am all for the Go idiom that variable name length should be directly proportional to it's scope, the code samples in the post have take it a bit too far and make the code harder to read.

it would be so much more readable if the struct had more descriptive names

    type Cuckoo struct {
       buckets           []bucket
       numBuckets        uint
       entriesPerBucket  uint 
       fingerprintLength uint
       capacity          uint
    }
