# Objective
Generated `from_reflect` methods use closures in a weird way, e.g.:
```rust
x: (|| {
<f32 as ::bevy::reflect::FromReflect>::from_reflect(
::bevy::reflect::Struct::field(__ref_struct, "x")?,
)
})()?,
```
The reason for this is because when `#[reflect(Default)]` is used, you
instead get stuff like this:
```rust
if let ::core::option::Option::Some(__field) = (|| {
<f32 as ::bevy::reflect::FromReflect>::from_reflect(
::bevy::reflect::Struct::field(__ref_struct, "x")?,
)
})() {
__this.x = __field;
}
```
and the closure is necessary to contain the scope of the `?`. But the
first case is more common.
Helps with #19873.
## Solution
Avoid the closure in the common case.
## Testing
I used cargo expand to confirm the closures are no longer produced in
the common case.
`-Zmacro-stats` output tells me this reduces the size of the `Reflect`
code produced for `bevy_ui` by 0.5%.
