Error if dot is used instead of colon at the start of block

[eglekaz]

In Progress it is always possible to replace the colon with a dot (even though it is very much not recommended!), and the code compiles and functions correctly.
It would be good to have it parsed as well.
Here are some examples:

define variable iEntries     as integer no-undo initial 4.
define variable iLine        as integer no-undo.
        
do iLine = 1 to iEntries - 1.
  message iLine.     
end.

class Testings:
  constructor public Testings(databasename as char):
    message "create " + databasename.
  end constructor.
  
  method public void stuff(  ).
    message "hi".
  end method.
end class.
