Feature or enhancement

CheckSyntaxError when doingdisplay inpdb.

Pitch

display adds an expression to watch list. However, if there's a syntax error, then the command is meaningless. Currently,display still adds this invalid expression into the watch list, which does not make sense in almost all cases. Adding a syntax error check could prevent the users from accidentally adding wrong expressions then having to remove it withundisplay.
