> For myself, I'm fine with the typing being in a separate .rbs file We type[0] by having one separate .rbs file per .rb file. Works really well with an editor's vertical splits: type outline on one side, code on the other. That, or use something like vim-projectionist[1]. We have a static typing guide for contributors[2], and I'm also accreting common errors and issues behind the scenes to produce a 'rbs+steep by example' to ease folks in.
