How to convert a path containing unix environment variable to an absolute path in perl?

Question

Let's say on my current shell, I have an environment variable - A_VAR set to "/tmp/"

I am defining a perl variable as (which is using A_VAR) -

my $path = "${A_VAR}/this/path/file.txt";

I am looking for a module which provides a function to convert $path to /tmp/this/path/file.txt

I would suggest just using A_VAR directly:

my $path = "$ENV{A_VAR}/this/path/file.txt";

If A_VAR may be non-absolute, that's a separate thing to handle - there are many modules that do this work, depending on how you like to interact with it. File::Spec, Path::Tiny, etc.
