I think Brett already answered this.
 
if (defined $x->{y}):
    [% IF x.y.defined %]

if (exists $x->{y}):
    [% IF x.exists(y) %]

Hmmm (reading the manual), maybe this would work.
 
[% IF x.$y %]
 
[% IF x.$y == 'foo' %]

Maybe I should restate. What is the perl template toolkit directive equivalent of:
 
if (defined $x->{y})
 
-- or --
 
if (exists $x->{y})
 
Thanks.

Combining constructs would be redundant.

Suppose I want to do an include only if something is defined,
how do I do it?
 
[% IF x.defined and x eq "foo" %]
    [% INCLUDE myfile %]
[% END %]
 
something like that? can't seem to locate it in the
man pages.
 
Thanks.
