KRL extended quotes support the beesting operator, making them simple templating systems. Inside an extended quote, expression values can be referenced using the #{<expr>} syntax. For example, suppose you've stored 10 and 20 in the variables a and b:

somevar = <<
The average of #{a} and #{b} is #{(a+ b)/2}
>>;

The value of somevar would be "The average of 10 and 20 is 15."

Non-Scalar Values

If you try to insert non-scalar values into a string using the beesting syntax, only their types will be printed. For a non-scalar, use the encode() operator on the value first to turn it into a string.
