Using fixed point in futil imports or function definitions doesn't work.

Futil imports

import futil("primitives/bitnum/math.futil")
{
  def std_sqrt(in: ufix<32, 16>): ufix<32, 16>;
}

let x: ufix<32, 16> = 4.0;

let t: ufix<32, 16> = std_sqrt(x);

->

ERROR: Stage 'dahlia' had a non-zero exit code.
---------------- stderr ----------------
[Error] [Line 8, Column 23] `std_sqrt` should be assigned to its own `let` statement, e.g. `let _temp = std_sqrt(...);`
let t: ufix<32, 16> = std_sqrt(x);

  return temp;
}

let x: ufix<32, 16> = 4.0;

let t: ufix<32, 16> = foo(x);

->

Use -l debug to get the stack trace and see which line in the compiler throws this error.

This is with fuse a.fuse -b=futil -l=debug:

[Error] [Line 8, Column 22] `foo` should be assigned to its own `let` statement, e.g. `let _temp = foo(...);`
let t: fix<32, 16> = foo(x);
                     ^

Not sure which part of the compiler is throwing it. Probably the code for EApp in futilbackend. That flag should’ve dumped the stack trace. See the CLI flags of the compiler to make sure it’s not log-level or something
