SPVM::Sys 0.26 is released - The Project for Python/NumPy Porting to Perl

SPVM::Sys 0.26 is released. You will see it in a few hours on CPAN. SPVM::Sys is a class for calling system calls such as File I/O, Socket, User/Group, Process. SPVM::Sys is developed on SPVM::Sys on Github.

For the Project for Python/NumPy Porting to Perl, SPVM::Sys is the basic class to read/write data from files.

What Is SPVM?

SPVM is a static typed language that can be used from Perl. SPVM is the essential part of the Python/numpy porting to Perl. If you haven't heard of Perl's SPVM. Please see also SPVM Language Specification.

How potential dose SPVM have?

Growth is expected in the fields of Bio Tech, AI/ML, Apple/iPhone/iPad Apps, Google/Android Apps, IoT Device, Connected Car, Smart Device, Smart Home, etc.

This is because SPVM can produce an executable file that supports cross platforms and make easy to calculate arrays and bind C/C++ and Nvidia/GPU/cuda.
