Having a typo in a alire.toml the corresponding error message does not point to the actual problem.

My alire.toml had the following lines:

[[depends-on]]
cortex_m = "~0.3"
hal = "#"
usb_embedded = "~0.3"
gnat_arm_elf = "^12"

The problem is in the line about hal. It is a typo and was supposed to read hal = "*".
The error message, however, did not make it clear (to me, at least) where the problem is.

❯ alr update
error: Cannot continue with invalid session:
error:    Loading release from manifest: alire.toml:
error:    Failed to load alire.toml:
error:    Unexpected symbol: # (at char 1)

I think it'd be helpful if the corresponding crate was mentioned, too. Perhaps sth like "[[depends-on]], crate "hal" has incorrect version"
