I also used Squirrel as a Lua replacement many years ago and also 
liked it in general. It was nice to have a companion scripting 
language with a C-style syntax for modding/extending the main C++ 
code. Unlike dealing with Lua, moving pieces of code between 
Squirrel and C++ required only minimal modifications. But I 
wasn't impressed with Squirrel's reliability and sandboxing 
capabilities. For example, having deep recursion in Squirrel 
could crash the host C++ application back then and I encountered 
other gotchas.

Today I would also possibly consider https://mruby.org as a 
possible Lua or Squirrel replacement. The security researchers 
had a field trip thoroughly looking for security/reliability 
problems in it: https://brandur.org/fragments/shopify-mruby
