| - | : //A mechanism to allow returning arbitrary-length data inside the EVM has been requested for quite a while now. Existing proposals always had very intricate problems associated with charging gas. This proposal solves the same problem while at the same time, it has a very simple gas charging mechanism and requires minimal changes to the call opcodes. Its workings are very similar to the way ''calldata'' is handled already; after a call, return data is kept inside a virtual buffer from which the caller can copy it (or parts thereof) into memory. At the next call, the buffer is overwritten. This mechanism is 100% backwards compatible.// | + | : //A mechanism to allow returning arbitrary-length data inside the EVM has been requested for quite a while now.
