The first part of the +alias meta may only contain the
name of the object, not its FQN. For example, here is how it may look in
EO:
+alias stdout org.eolang.io.stdout
# Basic object.
[] > foo
stdout
"Hello, world!\n"Here, the stdout part of the +alias meta is
the name of the object used later in the code. It will automatically be
replaced with org.eolang.io.stdout.
The error may also indicate incorrect usage of the
<meta> element in XMIR. The alias defined above must
look like this, in XMIR:
<program>
<metas>
<meta>
<head>alias</head>
<tail>stdout org.eolang.io.stdout</tail>
<part>stdout</part>
<part>org.eolang.io.stdout</part>
</meta>
</metas>
</program>Here, the part elements in the meta element
must be used to define separate parts of the +alias
meta.
