In 2.x.x bareword left operand is assumed to be an attribute reference. Right
bareword operand is assumed to be a number literal, or a member of the set of
string values associated with an integer attribute.
LHS/RHS operands are not interchangeable in their roles.

It's a string expansion, string expansions only function inside double quotes.
This is similar to variable expansion in most scripting languages.

Man unlang
VARIABLES
Run-time variables are referenced using the following syntax
%{Variable-Name}
Note that unlike C, there is no way to declare variables, or to refer to
them outside of a string
context. All references to variables MUST be contained inside of a
double-quoted or back-quoted
string."
