+=head1 NAME
+
+Test::Leaner - A slimmer Test::More for when you favor performance over completeness.
+
+=head1 VERSION
+
+Version 0.01

+=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.
+Its functions behave the same as their L<Test::More> counterparts, except for the following differences :
+
+=over 4
+
+=item *
+
+Stringification isn't forced on the test operands.
+However, L</ok> honors C<'bool'> overloading, L</is> honors C<'eq'> overloading and L</cmp_ok> honors whichever overloading category corresponds to the specified operator.
+
+=item *
+
+L</pass>, L</fail>, L</ok>, L</is>, L</isnt>, L</like>, L</unlike> and L</cmp_ok> are all guaranteed to return the truth value of the test.
+
+=item *
+
+L</cmp_ok> throws an exception if the given operator isn't a valid Perl binary operator (except C<'='> and variants).
+It also tests in scalar context, so C<'..'> will be treated as the flip-flop operator and not the range operator.
+
+=item *
+
+C<use_ok>, C<require_ok>, C<can_ok>, C<isa_ok>, C<new_ok>, C<subtest>, C<explain>, C<TODO> blocks and C<todo_skip> are not implemented.

+=head2 C<tap_stream [ $fh ]>
+
+Read/write accessor for the filehandle to which the tests are outputted.
+On write, it also turns autoflush on onto C<$fh>.
+
+Note that it can only be used as a write accessor before you start any thread, as L<threads::shared> cannot reliably share filehandles.
+
+Defaults to C<STDOUT>.
