Regression from 2.049->2.050, using rdmd.d r1400:

std.contracts has been scheduled for deprecation. Please use std.exception instead. rdmd.d(186): Error: template std.algorithm.startsWith(alias pred = "a == b",Range,Ranges...) if (Ranges.length > 1 && isInputRange!(Range) && is(typeof(.startsWith!(pred)(doesThisStart,withOneOfThese[0])) : bool) && is(typeof(.startsWith!(pred)(doesThisStart,withOneOfThese[1..__dollar])) : uint)) does not match any function template declaration rdmd.d(186): Error: template std.algorithm.startsWith(alias pred = "a == b",Range,Ranges...) if (Ranges.length > 1 && isInputRange!(Range) && is(typeof(.startsWith!(pred)(doesThisStart,withOneOfThese[0])) : bool) && is(typeof(.startsWith!(pred)(doesThisStart,withOneOfThese[1..__dollar])) : uint)) cannot deduce template function from argument types !()(const(immutable(char)[]),string) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Put a reduced test case for this in issue 5134. Made it a separate issue
because I think that might be non-trivial to solve, whereas this should be easy
to work around.

Workaround:

Change line #183 from:

bool inALibrary(in string source, in string object)

to:

bool inALibrary(string source, in string object)

I mentioned this also on the beta mailing list; the direct cause are the
changes done by David Simcha to avoid code in phobos that relies on issue 3534.
I also got this problem for startsWith, but almost all functions working with
ranges should be affected by this.

David also proposed a language fix for this that sounds promising, although I
did not really think through all the implications:
http://www.digitalmars.com/d/archives/digitalmars/D/Proposal_Automatic_shallow_Unqual_on_IFTI_113653.html

The alternative would be to change all functions dealing with ranges that have
this issue.
