(1) -> ?foo x == x + x
Type: Void
(2) -> ?foo 3
There are no library operations named foo
Use HyperDoc Browse or issue
)what op foo
to learn if there is any operation containing " foo " in its
name.
Cannot find a definition or applicable library operation named foo
with argument type(s)
PositiveInteger
Perhaps you should use "@" to indicate the required return type,
or "$" to specify which version of the function you need.
(2) -> <<bar x == x + x
Type: Void
(3) -> <<bar 3
There are no library operations named bar
Use HyperDoc Browse or issue
)what op bar
to learn if there is any operation containing " bar " in its
name.
