What is the real-world use case of this "feature"? I mean,
everyone knows what the code they write looks like, so why
would they want to have a language feature to get a string
representation of it that they can print out to the user? I
mean, if at all someone wants to print out 1 + 2, they can
always say "1 + 2" and be done with it, instead of going to the
convolution of .stringof...
One thing I observe however is that:
writeln((1+ 2).stringof);
writeln((1 +2).stringof);
writeln((1 + 2).stringof);
all print "1 + 2" (without the quotes) so it's not a simple
compiler dumps to string thing, but still I don't understand
what this can be useful for...
It could be useful combined with mixins to preprocess the code
you write before compiling it.
