I have code that generates arrays of mutable chars, and I have to convert them to BigInts. I'd like this to be allowed:

import std.bigint: BigInt;
void main() {
    char[] s1 = "123".dup;
    assert(BigInt(s1) == 123);
    char[] s2 = "0xABC".dup;
    assert(BigInt(s2) == 2748);
}


DMD 2.060alpha gives:

...\dmd2\src\phobos\std\bigint.d(97): Error: function
std.internal.math.biguintcore.BigUint.fromHexString (string s) is not callable
using argument types (char[])
...\dmd2\src\phobos\std\bigint.d(97): Error: cannot implicitly convert
expression (s[2u..__dollar]) of type char[] to string
...\dmd2\src\phobos\std\bigint.d(99): Error: function
std.internal.math.biguintcore.BigUint.fromDecimalString (string s) is not
callable using argument types (char[])
...\dmd2\src\phobos\std\bigint.d(99): Error: cannot implicitly convert
expression (s) of type char[] to string
test.d(4): Error: template instance std.bigint.BigInt.__ctor!(char[]) error
instantiating


Current workaround: I use a cast:

char[] s1 = "123".dup;
assert(BigInt(cast(string)s1) == 123);
