Precedence issue, so use parens to disambiguate. 

grep /testme/, @array ? qq! yes ! : qq! no !

[download]

means 

grep /testme/, ( @array ? qq! yes ! : qq! no ! )

[download]

You want 

grep(/testme/, @array) ? qq! yes ! : qq! no !

[download]

or 

(grep /testme/, @array) ? qq! yes ! : qq! no !

[download]

Update: AnomalousMonk mentioned "Perhaps make clear that both solutions need to be enclosed in original set of parens to work."

Replacing 

grep /testme/, @array ? qq! yes ! : qq! no !

[download]

with 

(grep /testme/, @array) ? qq! yes ! : qq! no !

[download]

means 

my $string = qq! first !
        . ( grep /testme/, @array ? qq! yes ! : qq! no ! )
        . qq! end !;

[download]

becomes 

my $string = qq! first !
        . ( (grep /testme/, @array) ? qq! yes ! : qq! no ! )
        . qq! end !;
