# What this teaches:
#   • Spread syntax — how to splice a collection into a list literal or function call
#   • Collection composition — building larger expressions by expanding collections inline
#
# Common mistakes:
#   • confusing sparge (splice) with appende, or using sparge on a non-collection expression
#

# sparge — spread a collection into another collection or call

# functio(sparge <lista>)          -- spread call arguments
#
# GRAMMAR:

#
# EXPECTED OUTPUT:
#   1, 2, 3, 4 (expanded list elements).

main {
    const _ media ← [2, 3]
