error diagnosis: range.algorithm(myFunc)

[Luís Marques via Digitalmars-d]

Hi,

I often type `range.algorithm(myFunc)` instead of the correct 
`range.algorithm!(myFunc)`. Would it be possible to improve the 
error message for this? Something like the compiler spell 
checker, and ask "did you mean `range.algorithm!(myFunc)`?".

That has happened sometimes with a non-UFCS call, but that's 
rarer, so just handling the UFCS case would bring most of the 
benefit, IMO.
