+1 (I'd even say that leading-comma style is the predominant one these
days thanks to [1] et al.)
Let's be a bit more conrete. Where everywhere shall leading+trailing
commas be supported, here's a few places OTTOMH, where comma-separated
entities occur which may or may not benefit from this treatment:
- list-syntax (+ even in pattern position?)
- module import/export list
- record syntax (+ patterns?)
- pattern-guards
- language pragmas
- ...?
