Weird exception on word Library

[evgygor]

When i use word Library whenever in code the weird exceptions appears.

Examples:
On

sub foo()
    library()
end sub

Appears: Parsing error: Expecting token of type --> END_SUB <-- but found --> 'Library' <-- at 2:5

================================================================
On

sub library()
   print "Hello"
end sub

Appears: Parsing error: Expecting token of type --> IDENTIFIER <-- but found --> 'library' <-- at 1:5

When I change the word "library" to any other like "kibrary, librar" no exception shown.
