Steps to reproduce
- Place the following code in
sandbox/eo/app.eo:
app.eo
+package sandbox
+alias stdout org.eolang.io.stdout
+alias sprintf org.eolang.txt.sprintf
[] > test
10 > c
[] > a
c > y
[args...] > app
stdout > @
sprintf
"Hello world"
- Compile it
Expected output
The program compiles successfully.

Analysis
Looks like access to c in the nested object test.a breaks the compiler, because when it is removed or when locator ^ is specified - the program compiles successfully.
The case looks even stranger, when trying to run the following program (example from paper):
Program
+package sandbox
+alias stdout org.eolang.io.stdout
+alias sprintf org.eolang.txt.sprintf
[child height] > shape
[] > volume
child.square.mul ^.height
[height r] > circle
memory r > radius
shape $ height > @
[] > square
3.14.mul
radius.mul
radius
[args...] > app
stdout > @
sprintf
"Hello world"
Because the program compiles successfully, even though it contains references to the upper level objects without an explicit locator in an inner object (circle.square references circle.radius relatively).
I can't understand why the behavior is as described, so I am submitting this issue in order to figure out what's happening.

I've repeated the steps in the description and the code has successfully compiled.
Current version of eo-maven-plugin (which I used):
[INFO] --- eo-maven-plugin:0.23.19:transpile (default) @ sandbox ---
The version in the description is:
[INFO] --- eo-maven-plugin:0.1.25:compile (default) @ quick-start ---
which is quite behind the current one.
Also both snippets in the description contains double line carriage which is not compilable with current version of the plugin.
@Sitiritis @yegor256 If the issue cannot be reproduced with new version of the plugin and corrected code - I suggest to close it.
@Sitiritis I'm closing. if any more similar issues, please open a new ticket
