Whereas the following alternative takes 20 ms :

see for yourself:

Could we not improve the syntax to something like:

     pragma(msg, format_jai("Hello %9", " I ", "
 just", " have" , " to", " concat", " a lot", " of", " strings
 ..."));
 }

Or whatever is closest that doesn't step on the current print syntax.

The point of format is that you want to replace the % my the argument and then write more static text.

"The Parameter '%' was null and it should not be"
"Rule '%' was not found in catalog '%' is possible the closest match"
