“Seems like it isn't ready for general usage yet.”
“there is no struct keyword in fusion it seems”
“It either takes a useless subset of all languages or do weird abstraction that wouldn't fit in a language otherwise.”
“the C portion expects an array of unknown size, no bounds checking possible at all”
“what I like the least in all kind of software is underdocumentation”
“I'm just wondering how to debug code written in fusion”
“I don't know if fusion is the solution”
“The syntax is so warm and simple, but not too simple.”
“It still feels overcomplicated compared to the standard solution of writing a library in a compiled language you like”
“I am sure writing code in fusion will produce C++ and Python code which is suboptimal”
“A universal language is hard to optimise for a particular language.”
