Generating a shape for
class_var.location
takes seconds because it is a union type more than 10 constructs.nil | RBS::Location[...] | RBS::Location[...] | RBS::Location[...] | ...
. Giving a typeRBS::Location[untyped, untyped]?
beforehand makes the shape generation much faster.This change makes type checking the
validator.rb
using released (and the HEAD) version of Steep faster. Not an improvement of the type checking algorithm itself.
