checks if two callExpressions are part of the same pipe
if not than checks if the second argument is a variable that is linked to the primary variable declaration
and will keep checking the second arguments recursively until it runs out of variable declarations
to check or it finds a match.
that way it can find fn calls that are linked to each other through variables eg:
const part001 = startSketchAt([0, 0])
|> xLineTo(1.69, %)
|> line([myVar, 0.38], %) // ❗️ <- cursor in this fn call (the primary)
|> line([0.41, baz], %)
|> xLine(0.91, %)
|> angledLine([37, 2], %)
const yo = line([myVar, 0.38], part001)
|> line([1, 1], %)
const yo2 = line([myVar, 0.38], yo)
|> line([1, 1], %) // ❗️ <- and cursor here (secondary) is linked to the one above through variables
