106Here is a example:

110=item B<matching for an item name>
111
112 @match hi
113 @cond grep $_->name =~ /royalty/, $who->inv
114 You got royalties there! Wanna have!
115
116You may want to change the C<name> method there to something like C<title>,
117C<slaying> or any other method that is allowed to be called on a
118C<cf::object> here.
119
120=item B<matching for an item name and removing the matched item>

122 @match found earhorn
123 @cond grep $_->slaying =~ /Gramp's walking stick/, $who->inv
124 @eval my @g = grep { $_->slaying =~ /Gramp's walking stick/ } $who->inv; $g[0]->decrease;
125 Thanks for the earhorn!
126
127This example is a bit more complex. The C<@eval> statement will search
128the players inventory for the same term as the C<@cond> and then
129decreases the number of objects used there.

131(See also the map: C<scorn/houses/cornerbrook.map> for an example how this is
132used in the real world :-)
