Like strWidth, but also strips ANSI escape sequences before
calculating the width.
This is no longer used in code, as widths are calculated before adding
ANSI escape sequences, but is being kept around for now.
Returns the precedence of default Haskell operators
Get the hash of a string.
This util is currently used to generate an
Int used for the

String)
Synonym for

error to be reserved for
programmer errors.
Alias for errorWithoutStackTrace (for base >= 4.9)
stop execution and displays an error message
raise a fatal internal error; message may have multiple lines
Same as
error but will make HDL generation fail if included in
the final circuit.
This is useful for the error case of static assertions.
Note that the error message needs to be a literal, and during HDL
generation the error message does not include a stack trace, so it had
better be descriptive.
