prefix patterns cannot be defined as constants

[Kai]

Hi there!

Just noticed that (shorthand and long) prefix patterns cannot be defined as constants. During a quick search I couldn't find this behaviour documented, so maybe it might be considered a bug?

Example:

define my_const = fc01:2345::/48+;

... returns a syntax error.

As does:

define my_const = fc01:2345::/48{48,128};

Best regards, Kai
