import std.metastrings;
import std.stdio;

void main()
{
  string s = Format!("Arg %s = %s", "foo", 27);
  writefln(s); // "Arg foo = 27"
}

template toStringNow(ulong v)
template toStringNow(long v)
template toStringNow(uint U)
template toStringNow(int I)
template toStringNow(bool B)
template toStringNow(string S)
template toStringNow(char C)
Convert constant argument to a string.

template parseUinteger(const(char)[] s)
Parse unsigned integer literal from the start of string s.

Returns:
.value = the integer literal as a string, .rest = the string following the integer literal

Otherwise:
.value = null, .rest = s

template parseInteger(const(char)[] s)
Parse integer literal optionally preceded by '-' from the start of string s.

Returns:
.value = the integer literal as a string, .rest = the string following the integer literal

Otherwise:
.value = null, .rest = s
