| Returns `true` if a source string matches one or more provided regular |

Do we know which regular expression is checked first? I mean, does it matter if it's matching the second or the fourth regular expression?

I'm not sure it matters from a usage point of view.
The expressions are checked using OR logic so if any of the regular expressions match, the function returns true.
The function also doesn't give any indicator of which expression matched. Only that at least one did.
match("explorer.exe", "[a-z]*?.exe", "[1-9]")
is equivalent to
match("explorer.exe", "[1-9]", "[a-z]*?.exe",)
