Re: NoSolution Virtual Machine
There's some advantage to being able to do this in most any language,
however Euphoria isn't as resource hungry as some other languages.
Of course C/C++ already implements some of these concepts , as most
any language must. Finding the balance between a multi-platform language
and concise low level code that has value for a variety of applications
is always a challenge.
The C/C++ standards take so long to eventuate , while in the meantime,
the capabilities of a particular minicomputer aren't being utilized
effectively.
Something like a standard C/C++ that lets you construct further
assembly level functions , that are called like most any other is one
possibility. This could be useful for Euphoria to , one simple example
augmenting sequence functions so that extended arithmetic etc , might
be performed. A sequence ( of arbitrary length ) , that might be
divided by 2 [ or multiplied by 2 ], with inter-bit/byte/word/sequence carry
being a particular example.
