# lambda of the message effect

# predicate of two conditions
[player has stone]->[player is op]

# do %lambda%
# executes a lambda

do [message "lambdas are fun :)" to player]->[message "code is life" to player]

# is the equivalent of

message "lambdas are fun :)" to player

# check[ed] %predicate%
# checks a predicate lambda

check [player has stone]->[player is op]

# is the equivalent of

if player has stone:
    if player is op:

# %objects% where %predicate%
# filters multiple objects that must match the predicate
# use the <type> input expression in lambdas here

loop all players where [player input has permission "test.test"]:

# is the equivalent of

loop all players:
    player has permission "test.test"

# you may now run a lambda instead of a command in formatted slots

format slot 1 of player with gold ingot to run [broadcast "lambda testing"]
