Qualified constants cannot be referenced inside bit array size segment patterns.

When pattern matching on a bit array, the compiler produces a syntax error if a qualified imported constant is referenced inside a size segment, for example:

import example/internal

const lap_data_size = 50

pub fn parse(bits:BitArray)->Result(_,Nil){
  case bits {
    <<
      lap_data:bytes-size(internal.maximum_cars * lap_data_size),
      time_trial_personal_best_car:unsigned-int-8,
      time_trial_rival_car:unsigned-int-8,
    >> -> todo
    _ -> todo
  }
}

This code produces the following error pointing to internal.:

Syntax error

I was not expecting this.

Found `.`, expected one of:
