Hello, could dipcli support array parameters, this is very useful.

solidity code:

function f(address[] memory addrs)

dipcli commands line:

dipcli vm call --from=xxxx \
...
--args="[$(dipcli keys show jack -a),$(dipcli keys show bob -a)]" \
--gas=9531375 -b block

sun:contracts/ (master) $ dipcli q vm call dip18dmyzdjl37lvl3jn2c5hzdnnflwwtzh4g5lsn6 dip1qv6qtq99996aea0fw09qeu9y0v48w3n5208khk qm ./receiver.abi --amount 0pdip --args=''

Hi！

A contract can have exactly one unnamed function. This function cannot have arguments, cannot return anything and has to have external visibility. It is executed on a call to the contract if none of the other functions match the given function identifier (or if no data was supplied at all).

Furthermore, this function is executed whenever the contract receives plain DIP (without data). To receive DIP and add it to the total balance of the contract, the fallback function must be marked payable. If no such function exists, the contract cannot receive DIP through regular transactions and throws an exception.

Like any function, the fallback function can execute complex operations as long as there is enough gas passed on to it.

In the current version, transferring funds directly to the contract will not trigger the execution of the smart contract code.

In some scenarios, such as auctions or crowdfunding scenarios, fallback function may provide convenience for developers and users. For example, users can transfer DIP directly to contract through wallets and interact with dapps without using browser plug-ins.

这会导致没有升级的节点继续按照前一个版本继续运行，当有一笔交易在新老版本有不同的逻辑时，老版本的程序会分叉，并且状态不可逆，导致节点必须升级后重新同步节点，会非常耗时。
升级失败的节点必须立即停止继续运行。
