Pun intended. Welcome to D, where 'enum' means 'const', 'const' means 
'readonly', 'lazy' means 'by name', 'assert' means 'assume' and 'real' 
does not mean 'real' (in fact, I really like the 'ireal' and 'creal' 
keywords, pity they are being phased out). :)

The wider context is that I have argued many times that it makes sense 
to put 'trivial' one-liners like this one into Phobos even if for no 
other reason than to standardize their names.
