Using keyword with dot in name using long format (e.g. MyLib.Keyword.with.dot) fails

[pekkaklarck]

If you have a library with a keyword with a dot in name like Keyword.with.dot using it without the library name works but prefixing it with the library name fails:

*** Settings ***
Library    MyLib

*** Test Cases ***
Example
    Keyword.with.dot    # works
    MyLib.Keyword.with.dot    # doesn't work

The reason that the latter doesn't work is that if there are dots in keyword name, possible library is always considered to be the part before the last dot. The motivation has been that you can have libraries with dots in name like org.robotframework.ExampleLibrary but dots in keyword names are very rare.

You can actually only have a dot in a keyword name when using the dynamic library interface where you can define the name yourself. Neither Python nor Java support having a dot in a method name when defining a keyword using the static library API. Because dots in keyword names are rare, and a simple workaround is avoid using them, this issue isn't too severe. Should definitely be fixed, though, because the current behavior is very inconsistent.

The problem is relatively easy to fix by splitting the given keyword name from all possible dots and testing does any library/keyword name combination work. Because string matching is blazingly in Python and keyword names used in test data typically don't even contain dots, there is no risk that this would somehow slow down execution speed.
