# Description
Fixes: #11287
Fixes: #11318
It's implemented by porting the similar logic in `eval_call`, I've tried
to reduce duplicate code, but it seems that it's hard without using
macros.
3ee2fc60f9/crates/nu-engine/src/eval.rs (L60-L130)
It only works for `do` command.
# User-Facing Changes
## Closure supports optional parameter
```nushell
let code = {|x?| print ($x | default "i'm the default")}
do $code
```
Previously it raises an error, after this change, it prints `i'm the
default`.
## Closure supports type checking
```nushell
let code = {|x: int| echo $x}
do $code "aa"
```
After this change, it will raise an error with a message: `can't convert
string to int`
