Introduces an annotation for the following declaration or statement.

# =============================================================================
# @ — Introduces an annotation for the following declaration or statement.

#
# What this teaches:
#   • Annotation syntax — `@ <name>` introduces an annotation applied to the following declaration or statement.
#   • Metadata annotations — annotations like `@ nondum`, `@ cli`, `@ futura` attach metadata to declarations.
#
# Common mistakes:
#   • Applying an annotation to the wrong declaration target — annotations apply to the immediately following declaration only.
#
# See also: nondum, cli, futura
