May be the way mathematicians notate is frankly ambiguous and confusing, and recent decades of programming experience have given good insight into more expressive methods of notation.
Structure and Interpretation of Classical Mechanics [1] walks through ambiguity in physics and math. The first interesting note I found was footnote 2 in the preface [2], citing the ambiguity in the statement of the chain rule.
I am ignorant about some of the insight coming from recent decades of programming and would love to hear it.

as opposed to recent millennia of mathematical experience?
