Thanks! I actually created a separate thread for that question:

> As discussed in [this thread](https://discourse.julialang.org/t/printing-of-unionall-types-is-misleading-as-of-julia-version-1-7/89418), printing of UnionAll types changed in Julia 1.7, as demonstrated here: 1.6 julia\> struct Foo{A,B} end julia\> Foo{Int} Foo{Int64, B} where B 1.7 julia\> struct Foo{A,B} end julia\> Foo{Int} Foo{Int64} Is there a way to recover the full UnionAll printing for Foo{Int}? Something like printunionall(Foo{Int})? (Obviously that doesn’t work, but you get the idea.)
