 ## Abstract
+
 Reduce the gas cost for call instructions, when the goal is to run a new instance of the currently loaded contract.
 
 ## Motivation
+
 The current gas cost of 700 for all call types (`CALL`, `DELEGATECALL`, `CALLCODE` and `STATICCALL`) does not take into account that a call to a contract itself
 does not need to perform additional I/O operations, because the current contract code has already been loaded into memory.

+Because of the `JUMP` usage for internal functions a smart contract languages are also at risk of reaching the stack depth limit considerably faster, if nested
 function calls with many in and/or outputs are required.
 
 Reducing the gas cost, and thereby incentivising of using call-to-self instead of `JUMP`s for the internal function implementation will also benefit static
 analyzers and tracers.
 
 ## Specification
+
 If `block.number >= FORK_BLKNUM`, then decrease the cost of `CALL`, `DELEGATECALL`, `CALLCODE` and `STATICCALL` from 700 to 40,
 if and only if, the destination address of the call equals to the address of the caller.
 
 ## Rationale
+
 EIP150 has increased the cost of these instructions from 40 to 700 to more fairly charge for loading new contracts from disk, e.g. to reflect the I/O charge more closely.
 By assuming that 660 is the cost of loading a contract from disk, one can assume that the original 40 gas is a fair cost of creating a new VM instance of an already loaded contract code.
 
 ## Backwards Compatibility
+
 This should pose no risk to backwards compatibility. Currently existing contracts should not notice the difference, just see cheaper execution.
 With EIP150 contract (and language) developers had a lesson that relying on strict gas costs is not feasible as costs may change.
 The impact of this EIP is even less that of EIP150 because the costs are changing downwards and not upwards.
