The Comment 6 example still fails to compile. It looks like the speculative
compilation in the `is(typeof(map))` wound up hiding the error in somefunc().

The code from the opening post now fails to compile in DMD v2.083.1 and the
linker won't be called. That's good.

But ag0aep6g's reduced case from Comment 6 --
https://issues.dlang.org/show_bug.cgi?id=15459#c6 -- still compiles with DMD
v2.083.1 on 64-bit Linux, then fails to link. Linker error below. Expected
instead: That code should fail compilation, as annotated via /* should fail
compilation */.

/usr/bin/ld: a.o: in function `_D1a__T3mapZQfFNaNbNiNfZv':
a.d:(.text._D1a__T3mapZQfFNaNbNiNfZv[_D1a__T3mapZQfFNaNbNiNfZv]+0x27):
undefined reference to
`_D1a__T9MapResultZQl6__ctorMFNaNbNcNiNfAaZSQBp__TQBqZQBu'
collect2: error: ld returned 1 exit status
Error: linker exited with status 1

Or should we file a separate bug for that?

I get:

test.d(13): Error: template `std.algorithm.iteration.each!(map).each` cannot
deduce function from argument types `!()(ByLine!(char, char))`, candidates are:
c:\cbx\mars\phobos\std\algorithm\iteration.d(890):   
`std.algorithm.iteration.each!(map).each(Range)(Range r) if
(!isForeachIterable!Range && (isRangeIterable!Range || __traits(compiles,
typeof(r.front).length)))`
c:\cbx\mars\phobos\std\algorithm\iteration.d(925):   
`std.algorithm.iteration.each!(map).each(Iterable)(auto ref Iterable r) if
(isForeachIterable!Iterable || __traits(compiles,
Parameters!(Parameters!(r.opApply`

So it works for me.
