* Hmmm, this is thoroughly meh, but I get to be lazy and not have make a new release for the crate:

```rust
let mut builder = at_commands::builder::CommandBuilder::create_set(buffer, true)
    .named("+CHTTPCREATE")
    .with_string_parameter("http://blabla");

if let Some(foo) = foo {
    builder = builder.with_int_parameter(foo);
}

builder.finish()
```
