In Lua, is there a way to check if a string is a valid PCRE pattern?

Examples:

local function is_valid_regex(pattern)
  -- Check if the pattern is PCRE-compliant
end

-- Test
print(is_valid_regex(".*"))       -- true
print(is_valid_regex("[a-z]+"))   -- true
print(is_valid_regex("([0-9]"))   -- false (unbalanced parentheses)
print(is_valid_regex("*invalid")) -- false (invalid usage of *)
