DMN18 — Missing FEEL function to replace in string without regex

The DMN specification provides a replace(input, pattern, replacement, flags?) function that requires a regex pattern as its second parameter. Regex are confusing to business users and some escape characters ends up preventing them from creating the logic they would like to implement.

A simpler function that replace a string content without regex would be highly desired.

For example:

string replace(input, match, replacement, count?)

This would allow to write a logic that replace strings containing regex special characters.

string replace("hello (name?)Unable to render embedded object: File (", "(name?)", "DMN") => "hello DMN) not found."

The optional count parameter is the number of occurrences to replace. A value of 1 mean the first occurrence, a value of -1 means the last occurrence, a value of 2 means the two first occurrences and the default value (not provided or 0) means all occurrences.
