+Symbols with built-in support in `grind` are unsuitable as pattern candidates for E-matching.
+This is because `grind` performs normalization operations and uses specialized data structures
+to implement these symbols, which may interfere with E-matching behavior.

+Auxiliary function to expand a pattern containing forbidden application symbols
+into a multi-pattern.
+
+This function enhances the usability of the `[grind =]` attribute by automatically handling
+forbidden pattern symbols. For example, consider the following theorem tagged with this attribute:
+```
+getLast?_eq_some_iff {xs : List α} {a : α} : xs.getLast? = some a ↔ ∃ ys, xs = ys ++ [a]
+```
+Here, the selected pattern is `xs.getLast? = some a`, but `Eq` is a forbidden pattern symbol.
+Instead of producing an error, this function converts the pattern into a multi-pattern,
+allowing the attribute to be used conveniently.
+
+The function recursively expands patterns with forbidden symbols by splitting them
+into their sub-components. If the pattern does not contain forbidden symbols,
+it is returned as-is.
