Dear Julia designers,
having read parts of the Applied Category Book Seven Sketches of Compositionality by Brendan Fong and David I. Spivak I really appreciate the use of the \fatsemi operator ⨟
It is just the reversed \circ ∘ function composition operator which is much more inuitive in many situations, because it rather mirrors how you would construct pipelines.
Unfortunately the character is not recognized by julia currently but instead if you try to assign to it you get the following error (julia 1.3.1)
ERROR: syntax: invalid character "⨟" near column 2
My suggestion is to add this character to valid characters and define it as the flipped function composition.
f ⨟ g = g ∘ f
