Review Comment:
Ah yeah so what I meant was that the current `parse_table_factor` gets
renamed to something like `parse_table_factor_inner`, then the actual impl
`parse_table_factor`, after parsing a lone `TableFactor` here
```rust
let table_factor = self.parse_table_factor_inner()?;
```
it next peeks if this table factor is actually a nested join, similar to the
current PR impl, and if it is, completes the parsing as a nested table factor
```rust
let mut table_factor = self.parse_table_factor_inner()?;
if self.peek_parens_less_nested_join() {
let joins = self.parse_joins()?;
table_factor = TableFactor::NestedJoin {
table_with_joins: Box::new(TableWithJoins { relation:
table_factor, joins }),
alias: None,
};
}
Ok(table_factor)
```
would this be reasonable?
