$distance={\sqrt {x^{2}+y^{2}}}$

-Fall 2022 Note: if attempted without pattern matching, you may receive an unresolved flex record error:
- ../../../main/sml/warmup_sum_distances_to_origin/sum_distances_to_origin.sml:4.2-21.56 Error: unresolved flex record (need to know the names of ALL the fields
- in this context)
-  type: {1:real, 2:real; 'Z}
-this can be solved by using pattern matching or specifying the type of the parameter xys:
