Which kind of verbs left to a derived function (e.g: v+/x) are parsed as first argument of the operator expression? ((/;+);`v;`x)
This seems true for lambda functions, projections and variables, while for basic functions e.g. -+/x this is (-:;((/;+);`x))
In the first case, this is "while" in the second case a monadic application.
