The function 'getAnywhere' crashes if given a non-existent name containing a period:

> getAnywhere( 'nomethod.noclassforme')
Error in get(x, envir, mode, inherits) : variable "nomethod" was not found

However, 'getAnywhere' behaves gracefully if the non-existent name lacks a period:

> getAnywhere( 'nomethod')
no object named `nomethod' was found

the latter being an object of class 'getAnywhere'.

The cause is actually in getS3method which isn't respecting the 'optional=TRUE' argument when it can't find any function to match its first argument. Whether this is strictly a bug in getS3method, I'm not sure-- but the side-effect in getAnywhere seems undesirable.
