would not it be nice to write []string{"hello}.Map(strings.ToUpper) ?
And so for userland types the language accept,
[]*MyType.Filter(func(*MyType)*MyType).Map(...).First()//etc.
IRL, because the total lack of such struct in the language might let you
think the idea is superfluous with the currrent
language/idioms/whateveryounameit,
I have this example i like,
// GetByID read the Tomate of given IDfunc (t Controller) GetByID(getID string)
(jsonResBody *Tomate, err error) {
t.backend.Transact(func(backend *Tomates) {
jsonResBody = backend.
Filter(FilterTomates.ByID(getID)).
First()
})
if jsonResBody == nil {
err = &NotFoundError{errors.New("Tomate not found")}
}
return jsonResBody, err
}
The code is not cluttered with extra if/else/for statements that i d have
to introduce using regular constructs proposed by the language.
What are the example that needs extended generic support that interface can
fulfilled ?
This one ?
type B string
func A([]string){}
func main(){
var x []B
A(x)
}
?
What else chan ?
https://gist.github.com/mchirico/df9fad3e7a5ea0c4527a ?
map ?
in all cases, it ends up with a manual conversion should occur, can t the
language handle it ?
Do the compatibility check needed to slice conversion and produce the
results or err appropriately.
Even better, take advantage of it to implement compilation rules ?
sX, err := conv([]string, x) or panic(err)
A(sX)
outChan, err := conv(<- chan /whatever compatible/, inputChan) or panic(err)
Are there more examples in sight ?
