Does it crash using If so, this is not a REPL issue, which would be greeeeeeeeeeeat, because we're throwing the current REPL out next week. |

@felixmulder Oh，you right. I try to add main method to the project: import org.glavo.dotty._
import org.glavo.dotty.Tag._
object Main {
def main(args: Array[String]): Unit = {
'html {}
}
} |
|
"yay"! :) |

Here is a minimised version of the code: object Main {
implicit def symbolToTag(symbol: Symbol): Tag = new Tag
def main(args: Array[String]): Unit = {
'html {}
}
}
class Tag {
def apply(attrs: (String, String)*): this.type = this
def apply(f: implicit Tag => Int)(implicit t: Tag = null): this.type = this
} |
|
Here is a simpler one, but the stack trace is different: object Main {
implicit def symbolToTag(symbol: Symbol): Tag = new Tag
def main(args: Array[String]): Unit = {
'html {}
}
}
class Tag {
def apply(attrs: (String, String)*): this.type = this
def apply(implicit t: Tag = null): this.type = this
}Maybe not the same issue? |

This fix prevents infinite chains of inserted apply's. Fixes scala#2960.
