Int used for the
internal pattern variable representation from the external pattern

String)
Raises an
error with a printf-specific prefix on the message
string.
Like the function
error, but appends a stack trace to the error
message if one is available.
The error used in
fixpointToFinal,
runFixpoint and
runFixpointM when the result of a failed computation is
recursively used and somehow visible. You may use this for your own
Fixpoint interpreters. The argument should be the name of the
interpreter.
Alias for errorWithoutStackTrace (for base >= 4.9)
