closedTrain emoji lambda operator
Description
Matz mentioned during the 'Questions for Matz' section at RubyConf 2013 that he would like to the train emoji as an alternative to the stabby lambda operator.
I have implemented this and attached the patch.
Example code:

Redmine truncated the sample code due to the use of emoji, so I have attached a sample file instead.

I had a look at https://bugs.ruby-lang.org/attachments/4038/train.patch.
Catching the 'train' emoji should be handled in the lexer, not in the
parser.
But first you have to make sure that the source file is actually UTF-8.
Also, when I looked at you first mail, I saw something that looked close
to a λ. Is that why this symbol was choosen?
Please note that there is nothing in the Unicode standard that says that
the symbol has to look like that, it can be a train looked at from the
front (see e.g. http://www.iemoji.com/view/emoji/847/places/train), or
any other representation of a train.
Also, as currently emoji characters are not that well supported, there
is quite some chance that the character gets rendered as a box or a
question mark, or not at all.

Currently I have no idea to include any method not operator whose name contains non-ascii characters in the core libraries.

This may imply that you have some ideas about implementing some
operators containing non-ascii characters. Can you confirm or deny?

It's fundamentally denial.
