MGCA: pretty printing for struct expressions and tuple calls
not sure
1. if there any tests that i need to adjust
2. if i should add any test for it
3. if humanity has come up with anything better than checking if that's first iteration or not with flag when printing sequences with separator
in case there is no tests for it and i dont have to add any, there is a demonstration of this ✨ pretty ✨ printing (this is output from `-Z unpretty=hir`)
```
fn test_errors<const N:
usize>() {
// accepts_enum::<{ None::<u32> }>();
accepts_point::<Point1 { a: N, b: N }>();
accepts_point::<Point(N, N)>();
}
```
btw it does not print const block
for this
```
accepts_point::<{ Point1 { a: const {N + 1}, b: N } }>();
```
it will print
```
accepts_point::<Point1 { a: { N + 1 }, b: N }>();
```
not sure if we want to print const blocks or not
