Line 23:
'''Description:''' Function to find the differences between members of an array. Comes in various flavors.
'''Examples:'''
<code>-':1 2 3 4 -> 1 1 1 1 /the builtin eachp prepends an array with zero before evaluation, so the output is the same size</code>
Line 30 ⟶ 31:
<code>{y/(1_;-1_)@\:x}[6 7 8;-] -> 1 1 /you can substitute the default eachp with your own for different behaviour, like this shakti example that just evaluates over each pair in x without prepending 0</code>
<code>-':6 7 8 -> 6 1 1 /the difference is highlighted here
