Feedback on ROM - Queries
First of all, the documentation for ROM is excellent! 👏 (both RDocs and guides)
The Projecting function results section inside the "SQL - Queries" guide shows adding function calls to the SQL query using this syntax:
int::count(...)
string::concat(...)
However, I couldn't find any clarification on this neither here nor in the rom-sql RDocs. I know that that this syntax is used for the SQL builder to know when you're adding a function call and when a column identifier (as both are method calls). But it would be great to have an explanation somewhere what are the typed int:: and string:: "namespaces" for, as I'm wondering why isn't there just a single function:: "namespace" 😃
Right, this should be documented. The reason why we require return type, is because we're inferring structs automatically, and we want to know both attribute names and their types.
One more thing, we have Any type, so it is possible to add a generic function builder that doesn't require return type, like the function:: syntax you proposed. WDYT @flash-gordon?
@solnic sounds like a nice idea. I think we could have fun for brevity.
