+// ParseError is returned when there is an error parsing the TOML syntax such as
+// invalid syntax, duplicate keys, etc.
+//
+// In addition to the error message itself, you can also print detailed location
+// information with context by using [ErrorWithPosition]:
+//
+//	toml: error: Key 'fruit' was already created and cannot be used as an array.
+//
+//	At line 4, column 2-7:
+//
+//	      2 | fruit = []
+//	      3 |
+//	      4 | [[fruit]] # Not allowed
+//	            ^^^^^
+//
+// [ErrorWithUsage] can be used to print the above with some more detailed usage
+// guidance:
+//
+//	toml: error: newlines not allowed within inline tables
+//
+//	At line 1, column 18:
+//
+//	      1 | x = [{ key = 42 #
+//	                           ^

+//	Error help:
+//
+//	  Inline tables must always be on a single line:
+//
+//	      table = {key = 42, second = 43}
+//
+//	  It is invalid to split them over multiple lines like so:
+//
+//	      # INVALID
+//	      table = {
+//	          key    = 42,
+//	          second = 43

+To prevent a '\' from being recognized as an escape character, use either:

+- a ' or '''-delimited string; escape characters aren't processed in them; or
+- write two backslashes to get a single backslash: '\\'.
