Erlang

Steps to reproduce

Run asdf. In help output a line is printed for the asdf env command:

asdf env <command> [executable]      Prints or runs an executable under a command environment

I would assume <command> is an arbitrary command. But from what I can tell needs to be a plugin name or a shim name? I'm also not sure how this differs from executing the shim directly.

FY

// ok
<<1:size(8)>>
<<1:size(x)>>

// not ok
<<1:size(7)>>

This won't catch all errors, because x could evaluate at runtime to a value that isn't a multiple of 8. However catching the literal cases when the term is explicitly an integer will still be valuable.

If a new Environment is created, processes inside of it will not have access to any command line arguments or environment variables by default. They need to be added to the ConfigEnv struct from which the Environment is created. Currently this is only possible from the host, but is not exposed as a [host function
