byLine/byLineCopy deprecation?

[bearophile via Digitalmars-d]

I have had few bugs caused by byLine not copying the line on 
default. Now we have byLineCopy, but sometimes I forget to use 
it. In D I prefer unsafe functions to be on request, and safe 
ones by default.

Originally I suggested to give to byLine a boolean template 
argument named "doCopy" that is true on default and can be set to 
false for performance:

So can we deprecate byLine and introduce something with a short 
name that is safer and something with a longer name that is 
faster (or probably better use just one function with the doCopy 
boolean template argument set to true by default).

A possible name for such function is "byRow!(bool doCopy=true, 
.....)" and then slowly deprecate byLine and byLineCopy.
