Why isn't set-builder notation used for defining functions?

In set-builder notation, we use | to show givens, yet there isn't really a standard symbol to show givens when defining functions. So why don't we just import the symbol from set-builder notation so that it becomes standardised?

That may be recognized in the Mathematics Subjects, or it may not be by all students. You certainly may use the | symbol from the keyboard.


However, for the purpose of general education it is preferable to refrain from “jargon” and special symbolism in most cases. Those may seem to be a simplification for experienced practitioners, but they are usually more confusing than helpful to new learners.
