* In [[APL\360]], [[SHARP APL]] and [[J]] stranding is called '''vector notation''' and is a part of token formation rather than execution. Only plain numbers are stranded. | * In [[APL\360]], [[SHARP APL]] and [[J]] stranding is called '''vector notation''' and is a part of token formation rather than execution.

* In [[A+]] a system equivalent to APL\360 is implemented, but is described as part of [[numeric literal]] notation. "Stranding" in A+ refers to vector notation using parentheses and semicolons <source lang=apl inline>(a;b;c)</source>. | * In [[A+]] a system equivalent to APL\360 is implemented, but is described as part of [[numeric literal]] notation.

* [[BQN]] breaks [[backwards compatibility]] with APL and does not allow stranding by juxtaposition even for numbers. Instead, the "ligature" character <code>‿</code> is used for a more explicit variation of stranding. | |||
An example in which stranding interferes with the most obvious way of writing a program is shown below. Consider applying the function <source lang=apl inline>f</source> to <source lang=apl inline>0.8</source> three times using the [[Power operator]]: | An example in which stranding interferes with the most obvious way of writing a program is shown below.
