silently - prevent any output from a block


=begin code :lang<raku>

use silently;

=end code


silently is module that exports a single sub called C<silently> that takes
a block to execute.  Inside that block, all textual output to $*OUT and $*ERR
is prevented from actually being sent to STDOUT and STDERR.


Note that if you're only interested in surpressing output from warnings,
you should use the C<quietly> statement prefix.


silently { say "hello world" }  # no output


my $captured = silently { note "tis wrong" }
if $captured.err -> $error {
    say "something went wrong: $error";
}


The "silently" subroutine takes a block as a parameter, and runs that block
catching all output to C<$*OUT> and C<$*ERR>.


If the output is actually needed for inspection: the subroutine returns an
object that provides two methods: C<out> and C<err>, giving the captured
output to C<$*OUT> and C<$*ERR> respectively.
