dslx parse error on expressions with inline for

[proppy]

Describe the bug

0003: fn foo(arg: bits[9]) -> bool {
0004:     let p = arg[8 +: u1];
0005:     p ^ for (i, acc) in u32:0..u32:8 {
~~~~~~~~~~~~~~^-^ ParseError: Expected start of an expression; got: keyword:for
0006:       arg[i+:u1] ^ acc
0007:     }(u1:1)

To Reproduce

fn foo(arg: bits[9]) -> bool {
    let p = arg[8 +: u1];
    p ^ for (i, acc) in u32:0..u32:8 {
      arg[i+:u1] ^ acc
    }(u1:1)
}

Expected behavior

expressions with an inline for are valid.

Workaround

Use a separate let binding:

fn foo(arg: bits[9]) -> bool {
    let p = arg[8 +: u1];
    let f = for (i, acc) in u32:0..u32:8 {
      arg[i+:u1] ^ acc
    }(u1:1);
    p ^ f
}
