I see following code from here:
+ val [ <category: 'math'> ^Complex real: (realpart + val real) imaginary: (imagpart + val imaginary) ] - val [ <category: 'math'> ^Complex real: (realpart - val real) imaginary: (imagpart - val imaginary) ]
These define methods/function of
-. I generally find the functions/methods are defined as follows (from here):
spend: amount [ <category: 'moving money'> balance := balance - amount ]
Why there is no
: (colon) after
- in code mentioned above?
Thanks for your insight.
