+# Emulate the is_numeric and validate_numeric functions
+# The regex is what's currently used in is_numeric
+# validate_numeric also allows range checking, which cannot be mapped to the string parsing inside the function.
+# For full backwards compatibility, you will need to keep the validate_numeric call around to catch everything.
+# To keep your development moving forward, you can also add a deprecation warning using the Integer type:
+#
+# ```class example($value) { validate_numeric($value, 10, 0) }```
+#
+# would turn into
+#
+# ```
+# class example(Stdlib::Compat::Numeric $value) {
+# validate_numeric($value, 10, 0)
+# assert_type(Integer[0, 10], $value) |$expected, $actual| {
+# warning("The 'value' parameter for the 'ntp' class has type ${actual}, but should be ${expected}.")
+# }
+# }
+# ```
+#
+# > Note that you need to use Variant[Integer[0, 10], Float[0, 10]] if you want to match both integers and floating point numbers.
+#
+# This allows you to find all places where a consumers of your code call it with unexpected values.
