Helper:

import Helper from '@ember/component/helper';

export default class ReturnTrueHelper extends Helper {
  public compute([value]: [any]): boolean {
    return true;
  }
}

HBS:

{{#if (return-true "foobar")}}
{{/if}}

Leads to:

This expression is not callable.
  Type 'ReturnTrueHelper' has no call signatures.typed-templates
