+Test::Leaner - A slimmer Test::More for when you favor performance over completeness.

+=head1 SYNOPSIS
+
+    use Test::Leaner tests => 10_000;
+    for (1 .. 10_000) {
+     ...
+     is $one, 1, "checking situation $_";
+    }
+
+
+=head1 DESCRIPTION
+
+When profiling some L<Test::More>-based test script that contained about 10 000 unit tests, I realized that 60% of the time was spent in L<Test::Builder> itself, even though every single test actually involved a costly C<eval STRING>.
+
+This module aims to be a partial replacement to L<Test::More> in those situations where you want to run a large number of simple tests.
