In my experience of Go, this is not actually true.
For example, in the latest project I've been working on, there
are 8487 lines of non-test code. In that code, there are
a total of 16 dynamic casts, more than half of which are checked
(mostly checking for particular error types). There are
a total of 4 occurrences which might possibly be amenable to generics.
The type system is totally relevant, and checks 99.9% of our code.
- copsarebastards 12y agoHow do you deal with container-type classes? The only way I can see to do this without casts is to duplicate the same container class for each contained type, which is fraught with its own problems.
