Summary0007409: meta-issue on type and path propagation
DescriptionThis meta-issue is meant to gather and reference issues that are related to the propagation of type information or type annotation during type-checking (typically for GADT typing and for disambiguation of type-ambiguous variant constructors and fields), as well as more syntactic techniques that also correspond to a propagation of path information (eg. turning { M.x = e1; y = e2 } into { M.x = e1; M.y = e2 }).

In GPR#285 ( [^] ), Frédéric Bour proposed to propagate when typing the argument of an application the result of unifying the expected return type of the application with the function-result type obtained by inferred the applied function expression.
