Which is a unfortunate common view.  It is a useful language and easy
to embedded in an application and not hard to learn.

I have used it in the coal mining machines I designed in a past life.

Users could enter their own calibration equations, like it was a
calculator, for doing sensors calibrations.
Many mines removed the factory supplied sensors, for reasons I never
understood, and replaced with their own.
So each sensor needed its own scaling that a user could enter and save.
