I got curious about this compiler and accessed their website.

It looks good, but it has a lot of shortcomings.

It also has some interesting extensions (C++ like) such as function
arguments by reference, function overload and templates, but the
function arguments by reference for instance uses copy to and from,
which is awkward and wasteful of program cycles and space.

The main shortcomings I found are:

- No #elif;
- Passing constant strings to functions first copy them to RAM;
- Crippled heap functions (maximum block length of 127 bytes);
- sprintf accepts only one variable (so not exactly a varargs list)
argument to be printed. Besides, the format specifiers are very
restricted and it can print 16-bit numeric values only. For 32-bit
values there is a sprintf32;
- It is not clear if it has a "printf" function, it has a lprintf which
prints to an LCD;
- Variables declared with the rom storage specifier can only be accessed
through the [] operators;
- rom variables can be used with char data types only;
- A rom pointer is internally limited to 8-bits: the constant array size
is thus limited to 256 elements

There are lots of other small "oddities" also.

Best regards,

Isaac
