=head1 SYNOPSIS
=head1 DESCRIPTION
When enabled (or disabled as some may prefer to say, since you actually turn it on by calling C<no indirect>), this pragma warns about indirect object syntax constructs that may have slipped into your code.
+
This syntax is now considered harmful, since its parsing has many quirks and its use is error prone (when C<swoosh> isn't defined, C<swoosh $x> actually compiles to C<< $x->swoosh >>).
+In L<http://www.shadowcat.co.uk/blog/matt-s-trout/indirect-but-still-fatal>, Matt S. Trout gives an example of an indirect construct that can cause a particularly bewildering error.
It currently does not warn for core functions (C<print>, C<say>, C<exec> or C<system>).
This may change in the future, or may be added as optional features that would be enabled by passing options to C<unimport>.
