Bug 8395 – Templated struct constructors don't implicitly convert to const

struct S { int m; // this(long x) // this(T : long)( T x) const this(T : long)( T x) { m = x;} } void main() { S s = 6; const S t = 7; } bug.d(18): Error: template bug.S.__ctor does not match any function template declaration bug.d(11): Error: template bug.S.__ctor(T : long) cannot deduce template function from argument types !()(int) If the constructor signature is replaced with either of the two commented lines, it compiles.

Therefore template constructor should work as like it. https://github.com/D-Programming-Language/dmd/commit/29c76d261fe81719addc0219c42b8fccc6562e88 Merge pull request #1060 from 9rnsr/fix8395 Issue 8395 - Templated struct constructors don't implicitly convert to const
