local r = sl.keys(sl) print(r)
--> table keys = {
argval,
null,
clrerrors,
probe,
convert,
geterror,
spin,
luo,
case,
ERR,
slversion,
macro,
keys,

}
Description
The helper function keystr returns human readable string representation of the keys found in its sole argument. The keys are converted to strings before concatenation into the resultant string. If the sole argument is not a table, then the string 'not a table' is returned.
