# import std.io as io
# import std.math as math

# Most of the syntax is the same as Tcl, except
# we have "simple lists" using "()":
set x [math (1 + 2 + 3 + 1)]
io.out $x
# → 7

# Contrary to Tcl, "{}" enclosed things are
# NOT strings, but simply a "SubProgram".
# They are parsed as any other part
# of the language, just not
# immediately run.

set d [dict (a 1) (b 2) (c 3)]

# Values can be extracted using Til extraction syntax:
io.out <$d a>  # prints "1"

# Extraction syntax is used to get values from lists, too:
set lista (a b c d e)
io.out <$lista 0>    # prints "a"
io.out <$lista 1 5>  # prints "(b c d e)"
