plural
Pluralize a string.
len $fish | plural "one anchovy" "many anchovies"
In the above, if the length of the string is 1, the first argument will be
printed (one anchovy). Otherwise, the second argument will be printed
(many anchovies).
The arguments are:
- singular string
- plural string
- length integer
NOTE: Sprig does not currently support languages with more complex pluralization
rules. And 0 is considered a plural because the English language treats it
as such (zero anchovies). The Sprig developers are working on a solution for
better internationalization.
