I did that for my HPC library and well, managing 457 such functiosn is a 
bit of a daunting task, but in the end it pays.
At some point you can factor out recurrent result into external class

Other nice thign is that turning this into a phoenix lambda is trivial, 
as for applying them to fusion tuples etc...
