Actually, CGI's import_names() method imports every parameter as a scalar
and as an array. The scalar will hold the first value for the parameter; the array will hold all the values, of course.
The array be safely used in all cases, but the scalar is available for when you know that a parameter should only have a single value.
% perl -MCGI -de '$q = new CGI "single=1&multi=1&multi=2";' -e '1;'
