\$\begingroup\$ @ArtemIce: There are supposed to be three boxes (quads). Two are the I/O variable (reading it gets input, and writing to it prints output), and one is in the name of the ⎕DL function which is sleep. \$\endgroup\$

\$\begingroup\$ Discussing on the APL Orchard, we wonder if ⌊∘⎕DL&¨ would count, for 7; removing the quad on the right makes it a function, ⎕DL is in the ISO SPEC for APL as delaying for "not less than" the time, so flooring its return value of "time actually delayed for" should be valid. \$\endgroup\$
