Lisp certainly does.

Or he meant to pass an optional parameter:

beans, jars, crates = secret_formula(start=point)

or an element access:

beans, jars, crates = secret_formula(start.point)

or a bunch of other possibilities.

since when did we start talking about lisp?

since when did we start talking about lisp?

Though not a lisper, the Python tie-in was my reply: Python (among
many other languages) doesn't allow a "-" as a character in
identifiers as you appeared to use it in your code. Unlike HTML,
XML, CSS, and apparently lisp and COBOL (thanks, MRAB, for ripping
open that scab after years of trying to repress those COBOL memories
where identifiers may contain the dash.

Or pass a boolean

beans, jars, crates = secret_formula(start>point)

Or subscript with an also-missing close-bracket

beans, jars, crates = secret_formula(start[point])

Or call a function with an also-missing close-paren

beans, jars, crates = secret_formula(start(point))

Or it was just a finger-flub

beans, jars, crates = secret_formula(startpoint)
