IdrisDoc: Control.ST.ImplicitCall

Control.ST.ImplicitCall

imp_call : STrans m t ys ys' -> {auto ctxt_prf : SubCtxt ys xs} -> STrans m t xs (\res => updateWith (ys' res) xs ctxt_prf)

Make 'call' implicit.
This makes ST programs less verbose, at the cost of making error messages
potentially more difficult to read.
