This is very strange. 'scl' is defined in "lib.l", before anything else
is loaded.

You invoked it from the Cygwin shell as 'pil', right? *Not* just the
bare 'picolisp' executable?

Not "atan2"? 'load' returns the value of the last expression in the
file, which happens to be the definition of 'atan2' here.

"@lib/math.l" sets the scale to a default of 6, so it should be all
right once it is successfully loaded :)
