yep.

yeah, and I have generally not gone anywhere near these, so I am a bit 
outside of the main Java demographic, but this may show in that I don't 
really use it all that often either (and usually then it has been 
incidental, like dealing with GWT or Android or J2ME).

yeah.


for another (incomplete) language intended more for use on embedded ARM 
targets, the logical string type was made to look like UTF-16, but was 
in-fact going to quietly use Windows-1252 for the underlying string 
representation in most cases, and the type would be quietly just a 
pointer to the first character of the string in the string table.

even as such, it is still too heavyweight to really be a good option for 
16-bit microcontrollers (C and ASM are pretty hard to beat here).


if one is looking at real-time embedded, some popular choices are C and 
C++, followed by Ada, Ladder Logic, and LabVIEW (these latter options 
being more common on things like PLCs and similar).


the language I was working on sort of resembled if C# used a syntax more 
resembling a Java/ActionScript3 hybrid, with modest tweaks, and use of 
RAII and explicit delete (more like C++).

unlike some of the other languages listed, the language was designed to 
more directly incorporate support for concurrent and asynchronous execution.

it was derived some from a parent language, but was getting a bit of 
tweaking and was being reimplemented mostly ground-up for the use-case 
(the predecessor was far too heavyweight to be viable even on fairly 
high-end embedded controllers, and in the redesigned VM).
