comment Strange setting in FormatValues[MakeExpression]
@Sjoerd yes I tried, but I want to avoid it, it's easy to use MakeBoxes and MakeExpression. But this is not the reason, the error/warning above shows up, because I started M. without loading any of may packages.

comment Strange setting in FormatValues[MakeExpression]
@Sjoerd But this is not may only setting, and I think to make |<stuff>| to be recognized as input, this wouldn't suffice.

comment Strange setting in FormatValues[MakeExpression]
@Sjoerd I want e.g. to print Abs[<stuff>] as |<stuff>| enclosed in \[LeftBracketingBar] and \[RightBraketinbar] in StandardForm, and I use MakeBoxes and MakeExpression for this.

comment Strange setting in FormatValues[MakeExpression]
@Sjoerd To make some output "prettier", I use FormatValues and I inspect them to see if everything is correct. BTW it seems, that the entry above does no harm, but if I spot an error/warning I´m curious where it comes from.

comment Is there a way to localize Off[some::message]?
@celtschk I use this mainly in packages, where I don't want to suppress all messages, but only those I know to be harmless in this case.
