Sequence: send message to itself or polling

[lixueyi83]

Often times, I need to send a message to itself or polling and in which case I need to do A -> A: polling, something like this:

┌─┐
│A│
└┬┘
 │
 │Polling
 │-----+
 │     |
 │<----+
 │
┌┴┐
│A│
└─┘

However, it seems it does not work here:

$ diagon Sequence -- "A -> A: polling"
Something went wrong!
free(): invalid next size (normal)
Aborted

Yes. This is probably the top 1 feature I would personally need.

I wonder if we shouldn't also support ordering the start and the end.

Proposed syntax:

1,2) A -> A: Task 1
3,4) A -> A: Task 2

A: 1 < 3 < 2 < 4

┌─┐
│A│
└┬┘
 │
 │ Task 1
 │---------+
 │         |
 │ Task 2  |
 │------------+
 │         |  |
 │         |  |
 │<--------+  |
 │            |
 │<-----------+
 │
┌┴┐
│A│
└─┘

That would be highly appreciated, and by the way, I just started using this fancy tool and it's really so fancy! I like everything to be simple, easy and does the job perfectly! Thank you very much!

just found this tool, it sure does seem to do most of the things i would need of a Sequence Diagram tool,
from a quick look this feature and a way to make a visual difference between async and sync calls is whats missing,
but i'll create another issue for that one.

keep up the great work @ArthurSonzogni
