Include constant in string without concatenating

How can I get a constant to be evaluated in a string like variables are?

$foo = "like";
define('BAR', 'fish');

// None of these give me 'I like to eat fish on Tuesday.'
echo "I $foo to eat BAR on Tuesday.";
echo "I $foo to eat {BAR} on Tuesday.";
echo 'I $foo to eat BAR on Tuesday.';

// This works but is undesirable
echo 'I $foo to eat '.BAR.' on Tuesday.';

As far as I know that isn't possibile. Check this answer here at SO, it contains useful workarounds if concatenation is so undesirable too you! Include constant in string without concatenating
