=head1 NAME
Catmandu::Fix::Bind::benchmark - a binder that calculates the execution time of Fix functions
=head1 SYNOPSIS
do benchmark(output => /dev/stderr)
foo()
end
# will create as side effect computation statistics on the stderr
elapsed command calls sec/comm
----------------------------------------------------------------------------------------------------
0.000006 Catmandu::Fix::foo 1 times 0.000006 secs/command
=head1 DESCRIPTION
The benchmark binder computes all the Fix function plus as side effect calculates the execution time
of all wrapped functions over all input records.
=head1 CONFIGURATION
=head2 output
Required. The path of a file to which the benchmark statistics will be written.
